I think it s not a hdparm problem....
my 2722 ist working with dma enabled in all 2.6.2 versions... at the 
moment I run 2.6.3-rc1-mm1 because of the airo modul

 From my config:
<*>     generic/default IDE chipset support
[*]     PCI IDE chipset support
[*]       Sharing PCI IDE interrupts support
[*]       Generic PCI bus-master DMA support
[*]         Use PCI DMA by default when available
[*]         Use PCI DMA by default when available

Did you get 2.6.3 to build?

hdparm output:

 hdparm -i /dev/hda |grep udma
 UDMA modes: udma0 udma1 udma2 udma3 udma4 *udma5
