Hmm...I built a new 2.0.21 with your latest patch, and it locked up just
the same...so I decided to take another look at CMOS settings. I turned
off several of the "performance" related items, booted with Drew's driver
to fsck the disk, then booted 2.0.21-bsd again, and just completed a make
zImage without locking up. That's the first time it's made it through a
kernel compile with the BSD driver in SMP mode.

Things I turned off are:
DRAM Speculative Leadoff
Turn-Around Insertion
Peer Concurrency
Chipset Special Features

I suppose the next things to do are test older kernels to see if they run
as well with these settings disabled, and then go back to 2.0.21 and start
enabling settings one at a time to see which is the "bad one". I'll go
try compiling a kernel with 2.0.20-bsd now.
