Comment # 11 on bug 1179387 from Stefan Dirsch

Hmm. Is 

 vga=0x317

no longer set? I believe Takashi wanted to know whether the generic framebuffer
is still working. So I suggest to try with

 vga=0x318 nomodeset

and then hardcode "fbdev" X driver.

Just using 

 video=1680x1050

will set the mode for KMS (kernel mode setting), *not* generic framebuffer -->
"modeset" X driver.

Also.

  hwinfo --framebuffer

will tell you the right mode for native resolution. This is not standardized
for resolutions > 1280x1024.
