OS X Crashed

Yup, another one. I’m getting very familiar with the kernel panic screen. I think I’m tracking it down, though. It seems to happen often (though not exclusively) in Safari when I’m trying to play Quicktime movies. I think it may have to do with the MOTU 324 drivers for my 2408 digital interface. I play all my audio out this interface all the time, and this seems to cause the crash (though, as I stated before, it’s non-reproducible in the same Safari movie).
I’m all updated as of today (w/repaired permissions) and I still got the kernel panic.
I tried to use the internal speaker on the computer and went back to the same site to play the movie. No crash. However I really want to use my mixer and speakers to hear audio (after all, I spent a lot on these things) so I plugged a cord into the back of the machine and router it into the mixer. I can hear the sound but I get a horrific amount of RFI from the computer itself, and This Will Not Do.
So I guess I’ll go back to using the 2408 and just putting up with the kernel panics. MOTU doesn’t mention problems and I haven’t heard of anyone else experiencing similar things. Familiar story: I’m off on my own desert island of technical problems and there’s no tech support lifeboat around- nothing to do but resigning myself to the next 1000 dinners from coconuts. I had hoped that the new computer would be a crystal clear and pristine start over, with no sneaky problems anywhere, but I guess that’s too much to hope for. Even for a Mac.

For what it’s worth, here’s the crash log:
