This is an area where you have more knowledge than I do.
I do only know people who don't have DMA support because you don't select "HPT366/368/370 chipset support" when you have a HPT374.
What about the patch below?

Adrian,
It is fine.
I just do not want to over represent the drivers capabilities.
Cheers,

Well that _used_ to be the case. But I just retested - the hpt374 under 2.5.56 is writing at a smooth 35 megs/sec to a single disk using UDMA6.
So it looks like something got fixed - it used to write extremely slowly unless I forced it back to UDMA5.
