Actually, this was the first vanilla kernel I tried on _this_
workstation. The earlier kernel came from Debian (testing).

It turns out I screwed up the kernel config which caused this. VIA PATA
driver was not used, but a generic IDE chipset driver :/ Probably it
didn't use DMA so the system became very sluggish.

The system is fine now. Thanks for your help, anyway.
