Well, after some time, I have tracked down the cause of my performance issues in Kubuntu 8.04. After the upgrade, I no longer have DMA on my hard drive.
I've got an older nForce motherboard, with an AMD Athlon XP processor.

The above link recommend using the amd74xx module, Except,...
~$ modprobe amd74xx
FATAL: Module amd74xx not found.
It appears to not be loaded on my system.
