Same motherboard here (except the Pro2 RU version, with USB 2.0 and
onboard Promise RAID). Using an Athlon Thunderbird 1GHz, 100MHz FSB
(10.0 multiplier).
So far looks good, has dropped CPU temp from 52C to 43C in a few
minutes, and this box is otherwise warm due to having four 7200RPM ATA
drives and full slots... I don't have ACPI in my kernel, but I do have
APM (although with only default options turned on).
I have no sound or X stuff on this system, so those things are not a
problem... I do have a Gigabit Ethernet card, though (NS83820-based), so
I will be curious if that is affected at all.
