Hi,

the new accelerated console drivers are indeed much faster (thanks for
the good work!), but there seems to be problems with Radeon Mobility
9700 and XFree86 4.5: starting X (from xdm) fails with the infamous

  xf86MapVidMem: could not mmap screen [s=100000, a=b0000000]
  (Operation not supported by device)

.  This seems to be different from the misfeature of the X drivers
OFB_FAKE_VGA_FB works around.  Any clues?  (My version of XFree86 has
a patched version of radeon_driver.c, but that patch should not break
anything before the mmap.)
