Yeah -- I've had this problem for a while, too. It started when
I upgraded my motherboard/processor to an AMD 486-80 on a SIS chipset.

To fix it, I've been using a patch that was posted to this list
a while back. The patch basically switches the processor back into
real mode and then jumps into the bootstrap code. It isn't a perfect
reset since the reset line doesn't get pulsed, but it does the job.
Somewhere around 2.0.4, arch/i386/kernel/process.c changed, and the
patch no longer applies cleanly. Maybe if I get some spare time, I'll
fix it up and repost it.
