Please show the output of hdparm /dev/hda:
/dev/hda:
multcount = 16 (on)
IO_support = 0 (default 16-bit)
unmaskirq = 0 (off)
using_dma = 1 (on)
keepsettings = 0 (off)
readonly = 0 (off)
readahead = 256 (on)
geometry = 65535/16/63, sectors = 117210240, start = 0
You will probably see using_dma = 0 there. This in turn probably means you
did not compile in the right IDE driver. Try hdparm -d1 /dev/hda, and/or
recompile your kernel.

You did not specify any details of your kernel compile so it is hard to
tell.
