I have the latest Koreader running on my Glo.
Basic functionality works, and is actually very nice.

Only in the configuration settings, when there is more than one page of options, I can't switch to the next page. Not sure whether that is supposed to work at this point.
I've added an icon to the reader menu. The one on the right (just the Home icon inverted) reboots the device. I prefer that over using the flimsy power slider.
Install into the .kobo - subfolder.
Run with ./kore.sh <path> from the shell.
Or use something like:
Code:
koreader= tweaks.executeSystemCmd(\"/mnt/onboard/.kobo/koreader/kore.sh /mnt/onboard\")
in kobotweaks.ini.
