But it is only a software thingy, not a hardware imposibility, that is what i
really wanted to know.
But then, if it don't work yet in X, then there must be another way to find
out. BTW, i guess the problem is in the sharing of the accel engine, where a
trick must be used like the 2nd head support in the G400, or the trick alan
implemented to support the gamma on both permedia3 of the jeronimo 2000 board.
What about work at the fbdve level ? Or a simple test program driving the
second head independently from the first, but not doing usefull stuff, just to
see it can work.
