Well, as it turns out, I think I oversized it

Partitioning, especially something like this, takes quite a bit of
forethought.  I ended up "aborting" the re-partitioning about half a
dozen times and restarting  [fortunately, the partition-table-rewrite
doesn't happen until you actually start the install...]

In the end, I had to wipe out the entire "LVM" partition and rebuild it.
I figured I would put the "hibernation" section in the highest-numbered
tracks [least used?] so noting that the LVM partition was 93.xxx GB in
size, I told SuSE's partitioner to make the new LVM partition "+90GB"
[the "+" tells the partitioner to "figure it out for me" so I don't have
to know the exact "last track number" for said partition]  I chose only
90 as I didn't want to end up in the case that the reported 3GB at the
end of the disk wasn't really 3GB (in other words, had I selected 91GB,
it's possible that the presumed 2GB remaining would only be 1.99GB,
which would be disasterous for a hibernation partition]

So, it's starting now -- should be ready right about lunchtime... (and
then I get to play with Xen...)
