I was having a similar problem.  I disabled cpuspeed and set acpi=off
in grub.conf and my X stopped freezing. (My box is a dedicated
mythbox, so this is ok with me, though not optimal.)

I still can't playback recordings though.  They start fine, but then
go to a pinkish fuzz pattern.
Do you get NVRM Xid errors in /var/log/messages:

Oct 16 22:59:06 myth kernel: NVRM: Xid (0001:0b): 13, 0000 01019700
00003497 00001808 00000000 00800000
Oct 16 22:59:06 myth kernel: NVRM: Xid (0001:0b): 30,  L1 -> L0

I'll try BOB and XvMC when I get home...
