Just to confirm it's not your imagination, I have similar symptoms 
this end. Two drives, with /dev/hda being an old 12G drive holding an 
XP install and a vfat storage space. /dev/hdb is a reasonably fast 
160G IDE unit.

When I use /dev/hda the system slows to a crawl. It wasn't always like 
this, the change happened when I upgraded from 2.6.11 to 2.6.15/16

So far, I don't have a solution for either of us
