ATI Rage Mobility P/M AGP 2x (Mach64), using stock driver as detected by
the installer (ati).

Well, if I can get the CPU to peg without even starting XMMS, why would
that matter?  But just for the sake of completeness, I've got a Crystal
SoundFusion CS 4614 sound card, using the cs46xx driver (whith
"thinkpad=1" passed as an option in /etc/modules.conf).

Incidentally, if I boot into runlevel 3 and then ssh in and run 'ls -lR /'
remotely, the CPU is fine.  If I start X (KDE, in my case) and run that
same command from a konsole window, the CPU usage spikes to 100% (looks
like X is about 60% and kdeinit is 30%, with the rest being ls).  If I run
GNOME and ran that same command locally, gnome-terminal likes to grab
about 85% of the cpu.  Running ls remotely while GNOME is up uses no
appreciable CPU.

XMMS skips when I run that command locally, playing either OGG or MP3
files.  It does not skip when I run it remotely.  I don't think the
problem is with XMMS.  Any other app (gkrellm, mozilla,
gnome-system-monitor, etc) all "skip" (eg, fail to redraw screen bits)
when the CPU usage approaches 100%.

I'll go file a bug report with bugzilla.
