For the actual rackmount machines, probably not, but I like having the
option.

Another machine is a desktop (w/rage128) and two more are laptops (w/old
radeon 7xxx [R100]), so I definitely want X11 running on them.

_I_ am not.  It's the result of whatever was changed with the introduction
of "options DRM_LEGACY".  I've built kernels with these configs since
NetBSD 5 with only minor tweaks to elide drivers for non-existent
hardware.  The last time I was able to successfully build these kernels
was 29 July 2022.

I seem to recall a mention that at present only "viadrmums" works with
the DRM_LEGACY option and indeed, I have a machine which uses that and
it builds fine.  I was hoping there was a way around that for the other
legacy DRM drivers, but unless/until they are adapted, I'll have to do
without.
