Miness 0x25, VP2/97 and pretty questionable. Locks up after an hour or two if I just enable DMA. I found `hdparm -X34 -d1' lets me use DMA without any hangs. Speed is markedly improved with it. Can't get UDMA at all though. Not a clue how. BIOS doesn't support it but disk does.
I don't know if the recent chipset tuning stuff helps. Haven't tried removing the -X34 to find out.
