I took the /proc/config.gz from the debian 2.6.18-1 kernel as the
base config for the 2.6.20-rc3 kernel and did a make oldconfig on
it to make sure it was valid for the newer kernel but pretty much
the same. I think that's the right process, so I don't think
different build configs are the problem here.

Cheers,

Dave.
