Well, that's funny, considering that for many people, it is the only
DRM port that actually works.

menu == many?  Where is this requirement documented?  Many people had
reported having to use `graphics/drm-legacy-kmod' ('cause, well, nothing
else works) and radeonkms.ko together with `x11-drivers/xf86-video-ati',
particularly, in PR 237642* about the invisible mouse pointer.

Wrong: both pfg@ and me did test those patches, as well as other people
who reported it on -x11@ list, with sad results unfortunately. :-(

Yes, lots of people apparently are happier with X11 server's built-in
"modesetting" driver rather than traditional xf86-video-*, but doesn't
modesetting drivers lack some/any 3D acceleration?  I don't see this
documented on wiki.freebsd.org/Graphics (and modesetting driver is only
mentioned in the Intel section).
