True, but from the pieces of discussions I've seen in #xorg-devel, I
doubt it's going to happen over a weekend. Also, similar problems in
the past were mostly just affecting software design decisions; this
one causes actual hardware problems.


[Though, personally, maybe the monitor-count check itself should be
possible to turn off, for unusual setups.]
