IBM has been guilty many, many times of this (as well as with buggy BIOS Int13h services too), which affected Western Digital as well until the switch to Hitachi (and IBM's sell-off to the same).
Intel's early ICH ATA for the i8xx chipsets, from the former PIIX ATA on the earlier i4xx chipsets also caused a lot of issues. But Intel worked them out rather quickly.
ViA has always horded it's specs, and Linux ATA issues plagued many of its early 82xx ATA logic, up until about 8233 or 8235.
AMD has only designed 1 ATA logic, the original one in the 751, and it is still used in the 760 as well as the AMD8111.
SiS used to be the same with its 551x ATA logic, although I have not tried its latest chipsets (since the Socket-462).
When I get home tonight I'll open up the box and re-seat the cables just to be sure that they are ok.
The exact make/model of your southbridge ATA would help -- use "lspci -v". If it is ViA, it should be VT823x. Get the exact model for me and I can help you more.
The exact output of "hdparm -i /dev/hda" and "hdparm -i /dev/hdb" would help as well.

Here are the model numbers of the mother board and chipsets:
