After thrashing around for days, I finally did a "write fail-safe
defaults" on my BIOS and the problem went away. It might be something to
do with MTRR use. This motherboard has a permanent AGP apeture (I guess
that's common to this intel graphics lineage) but some configurations
use up 3 MTRRs in BIOS and the bad configuration uses 7. It'll take me
a while to figure out what the problem was.
