No.

matroxfb_swapped does not touch videomode, so it is really surprising
that it clears yres for you. It only says which CRTC is connected
to which OUTPUT.

Can you do:

fbset -fb /dev/fb0
matroxset -f /dev/fb1 -m 0
fbset -fb /dev/fb0
matroxset -f /dev/fb0 -m 2
fbset -fb /dev/fb0
matroxset -f /dev/fb0 -m 0
fbset -fb /dev/fb0
matroxset -f /dev/fb0 -m 1
fbset -fb /dev/fb0

and post output here? I do not see any reason why matroxset should clear
yres/yres_virtual unless you already did not have yres_virtual at zero
before (then it will clip yres to yres_virtual, making it zero too).
