If this is indeed the problem (ACPI), why didn't it affect .16?  I would 
be willing to take it out of my kernel, except I really don't want to 
recompile.  Anyone know if just setting acpi=off in lilo.conf will do 
the same thing?  I will try it, but I don't really want to recompile 
with opengl enabled again unless this is sure to work.
