which is

  Look at `find . -name ucb1\*` in the kernel tree
  and watch how everybody has written the driver
  once again for his priceless board.
2. Makes the move to 2.6 easier
3. Helps to populate /lib/modules/* on the

Thanks for pointing me to the pcmcia power problem,
i have oversimplified the things.
We have three (well, 4) non-generic files now:
init.S, jornada820.c, pcmcia/sa1101_jornada820.c and
powerd-jornada820.c. The last one should export the
apm interface, like apm.c, and provide the rest to 
The backup battery driver will be j820 specific too,
and whatever is on the UCB1200 GPIO pins.
I still don't understand how to control brightness/
black level/backlight portably. How do ipaq people
