Digital noise on Delta 1010 outputs

Keeping the CPUs busy seems to get rid of this:
cat /dev/zero >/dev/null

So it's something with the power management.  Maybe switch acpi off at
boot?

This also fixes the jack problem.
Got latency down to 96000 kHz, 64 samples, 2 buffers = 0.7 mS
That's pretty decent.

TODO:
 - acpi off at boot (EDIT: doesn't make a difference)
 - remove HD54xx card (use built-in HD4xxx)  (EDIT: works)


sudo m-a -l 2.6.31.12-rt21 -k /usr/src/linux-headers-2.6.31.12-rt21 a-i fglrx
