There is bluetooth support in the kernel for the right chip, dunno if Android supports it though. Maybe Solca can tell us more how or if did he got it to run?

As for qwerty.kl - there is a second file with the kernel archive - omap-keypad.kl, you should place it in /system/usr/keylayout/ (or symlink the Internal_keypad.kl). Do the same for Internal_keypad.kcm.bin in /system/usr/keychars/ (you should symlink it as omap-keypad.kcm.bin

Adb is unstable due to low memory. Maybe when Solca does the stripped userspace (we don't need 1.2MB phone service at all and some more too).
