Bug#577976: xserver-xorg-video-vesa: New VESA driver excrutiatingly slow

I have no idea whether that would make any difference, but can you
check what happens if you install libgl1-mesa-dri? (For some reasons a
dlopen is attempted on swrast_dri.so)

You may want to check what happens with fbdev instead?
