I'll try that, but it looks like it wouldn't be an ideal solution,
because it's still version-specific.
That is, it might work fine for one particular occurrence of the "new X"
problem, but what happens when another new X comes along later? Wouldn't
I see the removal attempt again, unless I go in and change the pinned
version manually?
What I was aiming at with the version-number wildcard is to let a single
pinning stanza work repeatedly, for different fglrx-driver versions,
without need for manual intervention.

I use apt-get, not aptitude, and I don't know whether it has a similar
option. I've never seen a comprehensive-seeming, but still readable,
listing of these apt-related config options.
(However, one of the most major reasons I don't use aptitude is because
of its penchant for suggesting removals - including, often, of the very
package(s) I requested to install/upgrade - as its first priority. It's
not impossible that this configuration tweak might mitigate that problem
to some considerable extent.)
