Oops, sorry. Didn't mean to be attributing incorrect information. My
apologies

Couple of things: I noticed that Adam added the '-s' option to the
modprobe command line, which logs data to syslog. Maybe something is
going wrong with this. Other possibility - I remember when testing my
kmod alterations that there were some odd occasional memory corruptions.
This was manifested by GPM registering mouse movements that I didn't make,
and failure of sh scripts that I know are correct. Try inserting some
dummy code into kmod and see if that changes the misbehavior. If it does,
we may have some (un?)-related memory trashing. You're using gcc 2.7.2.3,
not egcs or gcc2.8, right?

Other thing - did the exact same setup work for 2.1.97 with Adam's patch?
Only because the patch is exactly the same. There might be breakage
elsewhere in the kernel.

Good luck testing,
