Does anyone know of any custom ROMs for kobo?

I really want to be able to overclock my kobo...

The custom ROM is an empty vessel; it is used, but never filled.
Oh, unfathomable source of ten thousand things!
Blunt the sharpness,
Untangle the knot,
Soften the glare,
Merge with dust.
Oh, hidden deep but ever present!
I do not know from whence it comes.
It is the forefather of the gods.

Better? :-)

They are working on getting the Vox able to accept a custom ROM in the hacking thread in the sticky section of this forum.

hieronymos is a person of many talents.

Actually, you don't need a custom ROM. Just a custom kernel. And we should have all the information we need to do this.
So you could:

a) Wait for Kobo to enable the GPU, then enable CPU scaling - and just overclock away.

b) Make your own kernel (there are good reasons Kobo explicitly disabled CPU scaling, mind you). Get the configuration from you Kobo at /proc/config.gz, find out what you need to enable in the kernel (asking the guys from SetCPU might be a good idea), get the kernel sources from Freescale, modify the configuration and start cross-compiling. Once you have the kernel, you just need to copy it to a certain location on the internal SD card that you took out of the Kobo, put the SD card back into the Kobo, power on and hope it starts. If something went wrong, you have of course the bytecopy stored on your computer that you can copy back on the SD card again.
Try to find out why, rinse, repeat.

All these steps are perfectly well documented - search terms like 'linux compile kernel' will come up with huge documentation on what you're about to do. A little trickier will be 'cross-compile kernel arm', but you'll manage. Freescale is self-explanatory, they have a great website.
The location where to copy the kernel is known and inside the hacking thread - reading the 6 pages of the thread might be worth the time, since there is a lot of interesting information.
If you don't like flash videos of flying cats, people who nag without wanting to contribute without anything, or people who absolutely don't tell you what they do during their 'incredible hacking progress' try to exclude 'xda' from your searches.

It's a great way to pass your weekend!
You also might find it interesting that there is a large amount of cheap Chinese tablets that ships exactly our processor, the imx515, on 1.2GHz. So that seems to be a reasonable clock rate.

Yes, in my experience with the imx515, 1.0Ghz runs very well ans 1.2Ghz runs (but maybe a little less stable?).

A custom ROM that works with an apk like ROM manager is still my ultimate goal. It makes it easy for average users to install and makes for easier backup, recovery, etc.

That said, I've been working almost exclusively on the kernel as of late. However, I'm holding off a little while waiting for sources and the first beta firmware.

I'm in my second 30 days :-/ And waiting for the uboot sources - don't they have a legal department or something? Already with the available documentation I'm not quite sure If I understand, and don't want to bump my head with screen initialization or something.
ROM manager and a full recovery are very useful even for me, although I'll let Kobo mess with Android.

No, really, as long as these things are documented it's quite easy. Just time consuming to really do the reading. Like a halogen lightbulb I exchanged the other day in a lamp that was already installed when we moved in. I opened the lamp and didn't even know what it was. Started tearing and turning. A few Wikipedia entries and YouTube videos later I knew how to take the thing out and even how to put a new one in (still managed to break the part on the bulb that had the wattage written on it, though).

The reason why people today are afraid of computers is because Windows only tells you that you need to contact your system administrator.
