@Frenzie: the kernel update was only a guess based on my (old) tinkering with that specific model. I still got one unit (with broken IR) running as a clock/weather panel. Since I can't get events from event1 (the touchscreen) I explored all the possibilities to generate inputs. Never noticed an "event2" so I though, ok, this is maybe a new kernel. It seems that I'm wrong.
@BloodRagg: if your time is limited then please repurpose stock os, if not the easiest way is building with buildroot with your local patches/branchs for specific package changes. Pleaste take in mind:
you need uboot only if you want to experiment with external booting (keeping compatibility with stock os) or you want to nuke the factory reset procedure.
you need the kernel only if you want to add a specific driver (like usb host support).
be my guess trying to install a new linux distro, but you'll need a devtmpfs enabled kernel, or somewhat create yourself device nodes and skip hotplug entirely.
If you want to distribute your work for others I will try to keep the changes at the minimum (repurposing most of stock os) and provide the neccesary patches as a KoboRoot.tgz, so you provide free software and not blobs that are shady or ilegal to share online.
