there could be many things wrong.  if you're having
a mtrr issue, then 9atom should fix it, since i gave mtrrs
a pass since they are depricated and require hooks into
the clock interrupt.

but i'm wondering if rio is the only thing that's choppy
on your system.  why don't you send pci output?  it's too
bad you don't have the 9atom mods to /dev/irqalloc that
would let us know if you have a ringing irq.
