Hi there,
Have an old Thinkpad 365X laptop that 'hdparm -i' tells me is
running mdma2 but it refuses to set dma mode. 2.6.16.18 also
refuses to set dma.

No luck with "hdparm -d1 /dev/hda" ??

Mmm.. there's a curious line: "PIIXa: neither IDE port enabled (BIOS)".
Can you enable DMA in the BIOS? The IDE driver seems to be unwilling
to set up the bus-master DMA (BMDMA) portion of the chip unless
it was already initialized by the BIOS (paranoia, I suppose, or maybe a bug).
Cheers
