Xorg and 5.0_BETA on Powerbook G4

[Tino Reinhardt <t%sdf.lonestar.org@localhost>]

Hi,

with 5.0_BETA GENERIC-kernel on a Powerbook G4 and
nVidia NV34M (GeForce FX Go5200) Xorg dies with:

  xf86MapVidMem: could not mmap screen [s=10000,a=a0000] (Invalid argument)

dmesg:

  genfb0 at pci0 dev 16 function 0: NVIDIA product 0x0329
  genfb0: framebuffer at 0xa0004000, size 1024x768, depth 8, stride 1024
  wsdisplay0 at genfb0 kbdmux 1: console (default, vt100 emulation)
  drm at genfb0 not configured

If configured to use ofb instead (custom kernel config)
it somewhat works if I put this in xorg.conf, as advised
by Xorg itself:

  Option "Protocol" "wskbd"
  Option "Device" "/dev/wskbd0"

dmesg:

  ofb0 at pci0 dev 16 function 0: NVIDIA product 0x0329
  ofb0: 1024x768, 8bpp
  wsdisplay0 at genfb0 kbdmux 1: console (std, vt100 emulation)
  direct rendering for ofb0 unsupportet

with kernel-config:

  ofb*     at pci? dev ? function ?
  options  OFB_ENABLE_CACHE
  options  OFB_FAKE_VGA_FB

Xorg works like a charm -- kernel-option "FONT_SONY12x24" is ignored
and Apples console-font remains unchanged and console keyboard is
unuseable after Xorg once run ... otherwise it's fun to use.

DPMS works and I just plug in my headphones and listen to music :-)

Thanks! --t,
