[PlanetCCRMA] IRQ problem, workaround

Hi all,

In addition to teaching, I maintain the language files and server for a 
university in Inner Mongolia. CCRMA has already made my life better. 
Thanks to everyone who works on the project.

Post install, booting 2.6.10-2.1.ll.rhfc3.ccrma caused udev (I think) to 
assign USB to IRQ 21 and the sound card. As soon as sound is 
initialised, USB is disabled. IRQ 21? that's a new one on me, as I 
thought only IRQ 2 was cascaded to provide IRQs 10-17. Anyway, since 
this is my first experience with a udev system, I am having to do some 
reading to figure out how to get USB to work under 
2.6.10-2.1.ll.rhfc3.ccrma. Any hints would be very helpful.

On the other hand, I have no trouble just booting 2.6.9-1.667 if I need 
to use USB. Not an elegant solution, but it works.

Thanks again for all the work on CCRMA.
