Judging by the pci ids database it's either an AMD Unknown or AMD Opus
chipset.

hdparm says DMA is enabled (it's enabled by a script a bootup AFAIK).

Installing smartd seems to have helped a lot - it's jumped to 28MB/32MB
which is a hell of a lot closer to what I was expecting (not sure if
ATA133 should give 133MB a second or whether that's just a theoretical
limit).

Not sure why enabling smart would help that much (I'm still working my
way around the BIOS settings and the way to enable it was far from
obvious - you have to do a manual config of the hard drive first).
