What does 'matroxfb_swapped' do ? You have not only yres_virtual, but also
yres set to 0. It looks to me like that 'matroxfb_swapped' asked for this...

Driver in kernel is identical to driver on my site, except that features
which are impossible to have with 2.6 fbdev kernel API were removed.
But for mere users who do not need fbset, different resolutions on each
display, textual displays or legacy svga games should not notice any 
difference.
