Yes, I for one can confirm that if you don't need anything else than to
populate /dev with nodes and maybe few
symlinks then mdev is perfectly fine.

I have run buildroot xorg with mdev without any problems.

*But* ... (and this is a big but) I have not tested how it reacts to
kernel events after boot when you *plug/unplug* devices and if mdev
is capable of *running programs/scripts when some event happens*.

If Funtoo can make it work and make it also work seamlessly with all the
other crazy stuff (network-manager, and some other
gnome stuff) then I will kick out udev from my system in a nanosecond :-)
