#hdparm -d /dev/hda

To enable it, use

#hdparm -d 1 /dev/hda

For what it is worth, here are the hdparm settings for my hard disk
(Western Digital Caviar SE WD3000JB-00KFA0, Parallel ATA):

#hdparm /dev/hda

 multcount    = 16 (on)
 IO_support   =  1 (32-bit)
 unmaskirq    =  1 (on)
 using_dma    =  1 (on)
 keepsettings =  0 (off)
 readonly     =  0 (off)
 readahead    = 256 (on)
 geometry     = 36481/255/63, sectors = 586072368, start = 0

Like you, I am cursed by the VIA chipset, but luckily I haven't experienced
any DMA lockups, which have been reported for many generations of VIA
hardware.  Every now and then, the system must be completely powered off,
because something apparently in the PCI controller gets misconfigured so
badly that Linux panics or hangs at boot.  The system reset or soft
power-off won't help in this situation.  Also, the system must be rebooted
in order for nvram-wakeup to work, and Wake-on-LAN often ceases to work.
This is an Intel Celeron 900 MHz on an MSI 694T Pro motherboard:

If everything else fails, try a hard power-off.
