Woohoo!  You rock!  I'm now looking at a 1280x1024x32 screen on this
same desktop machine, admirably panic-free since applying your
patches!

When I launched the X -configure this time, it printed the following stuff
out on the console:

MSR 26e, old=1515151515151515 new=101010101010101
MSR 26f, old=1515151515151515 new=101010101010101

Apr 9 13:02:06 freebsd /kernel: MSR 26e, old=1515151515151515 new=101010101010101
Apr 9 13:02:06 freebsd /kernel: MSR 26f, old=1515151515151515 new=101010101010101
Apr 9 13:02:06 freebsd /kernel: MSR 26f, old=1515151515151515 new=101010101010101

Mike Smith would certainly be the man to review your patches since he wrote
much (all?) of the original MTRR code.
