This patch makes the kernel's interrupt handlers into separate visible
threads, which can then be given different scheduling priorities. rtirq
is a script which automates interrupt handler prioritization optimised for
audio use. Basically, this does in software what you want to do in hardware,
it seems.  (From reading

more knowledgable than I am on the subject! ;-)

My own preference would be kernel tinkering over bios tinkering, *by far*
because it's far safer - especially when the exact bios to use is in doubt
(if indeed there is one with the capabilities you want). Loading the
wrong bios can be a non-recoverable error!
