This is probably caused by the disk supporting UDMA/100 and the
quirk of the VIA pciide where you can't tell from the chip
revision which modes it supports.

Can you cross-build a new kernel?

If so, try disabling ATA DMA in the kernel configuration like this.

-wd* 		at pciide? channel ? drive ? flags 0x0000
+wd* 		at pciide? channel ? drive ? flags 0x0ff0
