What does Windows 2000 report it's CPU usage at?

Does the problem appear with only a single CPU (and preferably a UP
HAL)?

GPLPV (which doesn't work on W2K) has an option to patch windows kernels
< W2K3SP2 to improve performance. Backporting just that part might not
be a huge deal, although the problem that fixes wouldn't cause 2 cpu's
to be pegged at 100%...
