First, I doubt that a) is realistic.  Why haven't the XFree project
themselves fixed the bug?  Probably because it is not "known" to be
buggy, that is, because there are only a very few people who have seen
it, and it depends on their complete hardware configuration including
the bus, clock speed, and gods know what else, so it is irreproducible
for the maintainers.  But for the people who have the bug it is
crucial that they can work around it by selecting another server.

As for b), if the system determined my card was S3V based and used that
information to filter down the choices just to
xserver-{svga,s3,xfree86} I would be happy.  But I don't know if this
is presently possible with debconf - i.e. can the set of choices be
generated on the fly?

Presumably all this matters only the first time X is installed, anyway
(afterwards it's trivial to simply upgrade the _existing_ server).
The first time, debconf's answer will be used by the setup script.
