As I wrote already - I got 2.6.7 to work (including some patches from 
hh/your cvs). The patch relative to clean 2.6.7 is not huge:
http://www.arava.co.il/matan/jornada820/2.6.7-my4.gz

I could not get any later kernel to boot, even to the stage that it 
gives me something on the serial port.
Recently, I tried debugging this issue (by changing printk to write 
directly to the serial port), and it seems that the problem appears to 
be with MMU initializing.

The CVS does not appear to build. After downloading 2.6.11 and appplying 
2.6.11.9 pathc, the compile fails with
