I clean forgot to explicitly affirm that it has DMA on:
kowari:~# hdparm /dev/hda

/dev/hda:
multcount    =  0 (off)
IO_support   =  0 (default 16-bit)
unmaskirq    =  0 (off)
using_dma    =  1 (on)
keepsettings =  0 (off)
readonly     =  0 (off)
readahead    = 256 (on)
geometry     = 16383/255/63, sectors = 234439535, start = 0
kowari:~#

I prefer u1 c1 but generally those make little difference.
kowari:~# hdparm -t /dev/hda

/dev/hda:
Timing buffered disk reads:   92 MB in  3.04 seconds =  30.23 MB/sec
kowari:~# hdparm -t /dev/hda{,,}

/dev/hda:
Timing buffered disk reads:  112 MB in  3.01 seconds =  37.17 MB/sec

/dev/hda:
Timing buffered disk reads:  108 MB in  3.05 seconds =  35.43 MB/sec

/dev/hda:
Timing buffered disk reads:  108 MB in  3.02 seconds =  35.73 MB/sec
