It worked! I suddenly see the convenience of disk labels - all I had to
do was tell fstab that swap was on /dev/hde3 and not /dev/hda3.
I wasn't able to boot rh7.2 on my other ata100 drive when I hooked it up
to the promise controller, even though I had the most recent kernel
installed and dmesg showed that it saw the controller. Not that it
matters, that drive is going into another computer.
Seems a little faster too (these are both 7200rpm ata100 drives):

/dev/hda:
Timing buffered disk reads: 64 MB in 2.65 seconds = 24.15 MB/sec
/dev/hde:
Timing buffered disk reads: 64 MB in 1.30 seconds = 49.23 MB/sec
