basically I hacked the voodoo3 driver not to try to save/restore the VGA textmode ( this causes the mmap error ) - but it leaves the problem with vgahw, switching resolutions / colour depth doesn't work at all. With a working vgahw module the textmode stuff would probably work too ( or at least not cause the mmap error anymore )
I used the official XFree86 4.3 sources.

good luck
