Okay, color me as having no idea what's going on...

Jiggered things around to boot from the drive connected to the Promise
(hereafter the old drive) again, with a copy of the original test
object (xfree86_4.2.1.orig.tar.gz from Branden's Debian archives).  It
still works with 2.4.23.  Rebuilt 2.4.22 (didn't have any of the patches
around, and I'm 99% sure I tested with 22-final just before giving up
originally); that works too.  Shutdown and physically removed the 3ware
card from the machine; dug up the grub boot disk that I'd forgotten I
would need for this, booted into 2.4.22 again.  Still, it works.

Maybe it's because the Promise chip knows it's no longer needed?  :-/
