There weren't really problems.

If you don't use HT, no problems I guess (I didn't try APM though,
but a GENERIC kernel runs fine).

I'm now running a ACPI kernel with MP support, without problems (thermal or

The onboard still has problems.

1.6.x should run fine.

This I can't comment on. The benefits of HT are not clear, and probably need
to be evaluated on a per-application basis, but even without HT the
dual-channel may still help (if done right, a device should be able to DMA
without blocking CPU access - but I didn't check this).
