Well, actually this seems to be somehow related to power management. If I 
boot with acpi=off, I'm not getting these xruns.
As I'd still like to use ACPI on this laptop, is it possible to disable it 
just temporarily while jack is running? Or is there some other way to 
keep ACPI from interrupting jack?
