No, I think perhaps "irq hungry" is a meaningless statement, rather
there's a nasty fight for resources between my AGP Rage card and the
Audiophile, I'm testing this simply by running Jack, and watching the
reports of xruns, the sblive is popping an xruns every twenty minutes, and
then the xrun is tiny like .009 miliseconds, while the Audiophile was
popping a 54 milisecond xrun every two seconds. The whole "irg
hungry" thing is perhaps a misnomer.

Well, I figured out that the culprit to my xrun
problem wasn't my 533mghz
processor, its my envy24 chipset based card, from the alsa wiki:
"Many but not all users complain about sound glitches. This may be due to
the cards being IRQ hungry. (VU meter interface?) -- Tobiah"
Given that the evil envy24 chip is in a lot of cards out there, I'm
wondering what cards people have had better results with?

Also, out of interest, what does IRQ hungry mean? Isn't the frequency
of interrupts determined by HW parameters you choose? How can there be
any 'extra' interrupts. You mentioned in an earlier thread that your
SB card didnt seem so interrupt hungry, but are you sure the device is
opened with the same params? I'm no expert. Can anyone explain this?
