Thanks to all who responded to this question. A few follow-up comments

One of these tickets recommending setting an option for the NVidia 
driver to disable a power saving mode. (For some users, with out this, 
graphics didn't work at all.) I figure it's easier to add it now, rather 
than trying to paste it in from a console later. Since adding it, it has 
made a very noticeable difference in the system's fan speed/run time. 
Clearly something I'll want to remove post-upgrade, if it isn't needed.

I noticed the release note about the MySQL upgrade, but don't anticipate 
a problem, as I'm not sure I'm using it for anything on this box. Lets 
see...nope, only the client libraries are installed.

I use 8.04 LTS for my MythTV back-end, so as to avoid disruption. Though 
8.04 is feeling rather long in the tooth these days.

Did you file a bug?

I haven't ran across that, but the  again I always do upgrades from the 
command line.

I used to stop and consider each of these prompts during an upgrade, but 
now I tend to just select the option to keep my customized version 
always. Post upgrade I then run a find command to show the config 
collisions and then at my leisure I merge the local changes (tracked 
with RCS) into the new versions, if there are useful updates, and 
generally clean up the temporary files. Someday I'd like to use 
something more powerful than RCS that could make the merge process less 
manual, like bzr.

Good to know.

I take it you couldn't find any "back" (forward) ports of 0.21 to 9.10?

I'm hoping with this upgrade I'll finally not have to build the ALSA 
driver from source after every kernel update. But I won't be surprised 
if that's still the case.

I don't have power management - specifically suspend/hibernate - working 
with 8.10 or 9.04 on the laptop in question, so if it doesn't work in 
9.10 I won't be any worse off. (As I recall the problem I had was that 
the video card didn't turn on after resuming. Probably something that 
can be scripted around, given enough time to experiment. I tend to keep 
the machine doing stuff most of the time, so I haven't felt compelled to 
solve this.)

Of course. The system gets its data backed up automatically, but this 
reminds me that I've never created a set of "bare-metal" recovery DVDs 
for it. Time to fire up Mondo Rescue.
