sound skips on linux ppc 2.6

I finally figured out why my sound was so flaky: apparently ALSA's emulation of OSS sucks in some way. The symptoms were that if I were playing music in XMMS and I wiggled the mouse around furiously (note: not even dragging a window, just causing X to send a lot of events), the audio would skip.

Once I had ogg123 -d alsa09 foo.ogg producing sound, reconfiguring gstreamer to use ALSA instead of OSS means that at least Rhythmbox (which I haven't really used in the past, but I dug up for the purposes of testing) works. XMMS, even with ALSA output, is still unreliable, but at one point I saw someone claim on a mailing list that it's some fundamental brokenness of XMMS.

Now if I can only figure out why it powers off instead of going to sleep, I'll have a computer that has technological innovation rivalling something out of the mid-nineties!
