Here's the info you wanted Michiel.

Doing a diff on the config of the bad kernel and the new one reveals this interesting tidbit...

diff -u 2.6.27-gentoo-r8-kernel-config.txt 2.6.28-gentoo-r2-kernel-config.txt
-CONFIG_BLK_DEV_IDEDISK=y
-CONFIG_IDEDISK_MULTI_MODE=y
+CONFIG_IDE_GD=y
+CONFIG_IDE_GD_ATA=y

That must have been what switched me back to using sda. Anyhow, that was obviously a separate issue.

So, my system performance, and io wait times are totally fine during normal system operation. When I do REALLY heavy io, the wait times go up, but the responsiveness is still relatively good. I can start kwrite in about 2-3 seconds. It seems like it is fixed to me. But, I'll still try that patched 2.6.28 and get back to you, to see if it is even better.

Perhaps Andrew Morton was right. Maybe my issue was entirely to do with my SATA issues.
