I should add that some of my motivation was wrong: I believed libudev
always required a running udev. A very easy misconception to make with
the naming, and with the responses I think others thought so too.

The subset of libudev used in mesa *does not* require a running udev,
or even installed udev. It's merely a /sys wrapper. Since this is
important to know, I would ask this be added into the documentation
(both docs/ and configure --help).

So with that cleared up, I have no big objections to requiring libudev
on linux. It should not be required for dri2 in general due to BSDs and
other such systems, though.
