More VIA chipset fun?

I'm getting the exact same symptoms, although our systems are somewhat different (still the VIA vt8233A southbridge, though):

Intel Pentium 4 2000Mhz (Northwood core)
Soltek SL-85DRV3 motherboard w. VIA P4X266A chipset Nvidia GeForce 2 GTS and SB Live
256MB DDR RAM
Kernel 2.4.19 w. XFS and pre-empt patches + Alsa 0.9 modules

I tried disabling both audio-support, rtc-driver and apm, but the lockup's still occur.

PS. Pleace cc me, as I'm not on the list.
