I'll try to do that tomorow, but last time I tried to recompile 2.6.10,
it failed, probably due to newer binutils in debian sid. Anyway, I'll
try to install an older toolchain to recompile 2.6.10.

I tried some other firmwares from the wiki and they either didn't work
at all (2.3.1.34) or failed the same way as 1.2.1.34.

I did that and it still oopsed, so I reverted to just returnin NULL, at
least it doesn't kill the machine and I can avoid rebooting.

By the way, I generated some logs with debug=0x20 

This is the last hostdesc printed before we find a corruption, it seems
to be corrupting when we return the the beggining of the ring buffer.
