@jgpmolloy I had a corrupted search box icon in the Finder. OK, will look into whether there's a way to update the audio stuff.
@jgpmolloy I don't think my speakers have drivers. The panic log seems to point to the graphics card.

@danielpunkass It will disallow the switch if there's an external display; or prevent detecting a display if you switch to Integrated first.
@glgray Thanks, but I need my external display.
@danielpunkass How did you do that? I'm assuming that won't work if there's an external display, though…
@glgray Yep, that's what I've got. 15-inch i7 MacBook Pro with 330M.
Getting really tired of these kernel panics due to Apple's GeForce driver. Started with Lion, I think.
