Okay guys, too late here so I'm posting my current progress.

http://www.bundyo.org/maemo/nitdroid...id_770.tar.bz2

Kernel and omap-keypad.kl in the archive. Use the last userspace from Solca. The kernel will run, but is still unstable - freezes from time to time, probably due to low memory. I'll see if i can get any swap there. Solca, why do we need phone and voice dialer in the user space? The phone is a service and takes memory too.

omap-keypad.kl goes to /system/usr/keylayout if you want to at least unlock the 770

Forgot to say - no wifi yet, since the driver is different.

EDIT: Its quite unstable yet, don't expect miracles...
