I'm trying the two new patches with 2.6 and my Award
bios which fixes the crash problem itself but didn't turn
on edge timer without a patch, and didn't turn on
nmi_watchdog=1 with the first patch, only =2.

nmi_watchdog gets a lot more ticks with =1, too.

I stayed with 600UL 100ndelay just to see if anything
breaks with amd XP3000+ and patches with a bios
that doesn't crash with nforce2 but needs help from
patches on other points(to get edge timer on and
to use nmi_watchdog=1 rather than =2). Also hope
we get a clue about what Award bios update does
that Phoenix does not do so far.
