I don't know if I'm up to the challenge of compiling my own kernels. I
haven't done that since about 1.2.x sometime... And that was just to
config in a driver. I'm an old PL/I & COBOL programmer, and quite 'C'
challenged.

  One item of note: this happens with amd_64 kernels only. Last week, I
did an installation of ubuntustudio on this machine, and was pleased to
discover that the LCD didn't go dim on me. But then disappointed to
discover that it installed a 32 bit kernel, and gnome. So I went back to
Kubuntu amd_64, then installed the ubuntustudio-audio packages (less one
that's broken on amd64) So it may be that some of that vga-init code
isn't 64-bit clean.
  There's another video bug open on this machine, but that has to do with
xorg properly detecting the widescreen 1280x800 mode, and is probably
unrelated to this lower-level vga bug.
