The current VIA driver in 2.4.0 is version 2.1e. I wouldn't push a new version, but VIA has released the vt82c686b chip and it's causing a lot of trouble. The 2.1e version can't recognize it from the vt82c686a, the only difference being the revision of the ISA bridge. This causes quite a lot of trouble, because the 686b chip has some significant changes in its UDMA programming, because it can do UDMA100. The 3.20 driver I'm sending a diff for is well tested and working nicely, also enabling the use of UDMA100 on the vt82c686b. On some vt82c586b's it fixes crashes and reboots, because it disables a certain dangerous feature (hold PREQ# till DDACK# unasserted), which BIOSes sometimes leave enabled. It also handles 8-bit (command) timing of the ATA bus better. I know it's a big change, but please put this patch either in 2.4.1 or in 2.4.2 - it'll help a lot of people and I'll be getting much less mails about non-working 686b's. It's against 2.4.1-pre12, but should patch cleanly against pre11 or anything later.
