Thanks a lot for replying!

route and hdparm fail here. Will try more later.

If your previous issue was about static linking, I solved it.
Actually, using an old ramdisk with the CVS kernel, pcmcia still fails.

Yes, that works; problem being that unless we can autodetect,
we can't have a one kernel to distribute.

OK. How else are we meant to detect it?
I'm playing with an autodetect routine in init.S; we'll see how well it works.

I got ATAGs working in init.S, which makes for an empty fixup_jornada820().

Question: if I use a compressed initrd, linux autodetects it properly,
but then seems to be reserving 7000-odd KiB instead of 3072 KiB
for the ramdisk...

It will help me make sure by myself that it won't help me :-)

Can you put a working 16MB zImage, too, so I may test my toolchain
from a working one? (Same question to George or Dave or anyone.)
