Seems to work for me when compiled into kernel on Commell LE365D (Via
CX700) though I get two unwanted effects:
- boot logo does not show up, where it should appear I just get a
  square of colored pixels (2 colors: background and foreground grid)
- when blanking console colored text remains visible (e.g. green '*'
  characters emitted during Gentoo boot)
  Ideally the output/monitor should got into standby when console is
  blanking


The boot logo issue exists when patch is applied to 2.6.26.2 and
2.6.27-rc2-git4, for the console blanking it's only tested on 2.6.26.2
as 2.6.27-rc2-git4 panics while probing hard drives.

Framebuffer related kernel commandline options:
  video=viafb:viafb_mode=1280x1024,viafb_bpp=32,viafb_refresh=60


Suspend to RAM (S3) works with BIOS configured to reinitialize the
graphics at resume time, I have not yet checked without this option
being enabled in BIOS (though it probably won't work as there is no
suspend/resume callback in the patch-set).
Have not checked yet if DRI has support for CX700 and can do the
suspend/resume handling as the intel DRI can do.


As Krzysztof Helt I'm in favor of merging and ironing out remaining
issues with incremental patches
