AFAICT, Resolved with 2.6.37 release, so updating as such.

I finally got some time to test with a stable kernel, and as of 2.6.37, as best
I can tell (this one bedeviled me to the point I'm reluctant to say it's for
sure fixed now, without a YEAR of it not coming back!), it's fixed.

The kernel comes back up and from CLI (there's major X corruption preventing
use of it after restore, but that'd be a different bug), I can dmesg, which
clearly shows (1) an initial failure to read the drive's ID info properly, as
before, but now, (2) instead of kicking it out to sde (with sd[a-d] normal) or
whatever as it did before, it apparently retries and comes up with the proper
ID, thus returning the drive to the proper sd[a-d] letter and its partitions to
the proper place in their assigned md/RAIDs.

On a slightly different note, a big THANKS! to whoever introduced and continues
maintaining magic-sysreq.  I had a hardware issue for awhile and at first
thought it was yet another pre-release kernel bug.  A bit of circuit-trace
paint later (expensive keyboard) and it's working fine again, but as often the
case, I didn't realize how much I took that feature for granted until it
failed.

And of course, thanks for getting the device-id detect and if necessary retry
working, too. =:^)

Now to see how 2.6.38 is coming along.  Maybe the radeon graphics
restore-state-on-resume works better now.  We'll see.
