Does the kernel report a supported IDE chipset during booting?

VP_IDE: VIA vt8233a (rev 00) IDE UDMA133 controller on pci0000:00:11.1

If it's a 2.6 kernel, check that /proc/config.gz contains the appropriate
CONFIG_BLK_DEV_ option. E.g. for my VIA-based mobo I have:

CONFIG_BLK_DEV_VIA82CXXX=y
CONFIG_BLK_DEV_IDEDMA=y

However the kernel usually doesn't let you enable DMA if it doesn't have
the correct driver - hdparm will say 'operation not permitted' or
something similar if you try to enable DMA in this case (hdparm -d 1). So
perhaps it's another problem.
