 Enabling sa1100fb.c with your patch, but not showing. I
wonder it is necessary to enable LCD with some GPIO. Then,
I need *blob*, I think blob is good tool for debug, too.

 I attached my patch. It's so quick hacking. Steps is shown
bellow.

1) Refer to http://acid.ch.pw.edu.pl/~sq5bpf/mylinux/linux-jornada720/
  And get linux-2.4.18-rmk2-hh2-jornada720.tgz

2) Extract his source, and take my patch.

3) copy arch/arm/def-configs/jornada820 .config

4) make vmlinux and gzip -9 vmlinux

5) Booting with hpcboot

Please try it, and hacking!!!
