An update, but it's not any better.
This is running Linux 2.3.99-pre4-5 while doing make -j 3 on same:
CPU states: 29.0% user, 14.1% system, 5.0% nice, 57.9% idle
CPU states: 32.6% user, 3.1% system, 4.0% nice, 65.3% idle
CPU states: 19.1% user, 2.5% system, 4.4% nice, 79.5% idle
CPU states: 65.8% user, 6.5% system, 5.6% nice, 29.3% idle
CPU states: 48.4% user, 9.5% system, 3.8% nice, 43.6% idle
CPU states: 56.7% user, 4.5% system, 4.4% nice, 39.9% idle
Since this is a dual-celeron, those numbers should add up to 200%.
Here's a full snapshot of top:

When it is truly idle, top looks like this:

rc5des is the distributed.net project, of course, and it does next to
no I/O. It should gobble up all available CPU-time. How can I tell
how much time is spent in spinlocks? (I assume some patch is needed :-)
