[Bug 57455] Re: Sound works sometimes on boot - sometimes not

Okay, here's the full details on the one where it does work, then:

SoupNazi has rev 01, and lolow's "Interrupt" is IRQ 50 (mine is 21).  I guess this is sort of a mix of bugs on different Intel sound cards, which all manifest similarly.  I'm guessing a similar line in /etc/modules would fix those cards too, I just don't know what to put.  I guess you could try different values for that model= part, but I'm going to go see if there's a bugreport upstream at alsa.
