Christian Trefzer 10ee39fe3f [PATCH] neofb: avoid resetting display config on unblank
Fix issues with the NeoMagic framebuffer driver.

It nicely complements my previous fix already in linus' tree.  The only
thing missing now is that the external CRT will not be activated at neofb
init when external-only is selected, either by register read or
module/kernel parameter.

Testing was done on a Dell Latitude CPi-A/NM2200 chip.

Previous behaviour:
- before booting linux, set the preferred display config X via FN+F8

- boot linux, neofb stores the register values in a private
  variable

- change the display config to Y via keystroke

- leave the machine in peace until display is blanked

- touching any key will result in display config X being restored

- booting up, the BIOS will acknowledge config Y, though...

Current behaviour:
At the time of unblanking, config Y is honoured because we now read back
register contents instead of just overwriting them with outdated values.
