I can trick mplayer with Xv to work now side-by-side by doing chvt 1 and
chvt7 (with the chvt fix which I just sent) before starting using mplayer.
I slight guess that this is might be related to the DPMS fix/hack with
last_mode which I sent initially because DPMS also works again after a
VC switch when the monitors are side-by-side. I guess that last_mode might
be wrongly set in that case, will check.
