- fixes the PCI-IDs (needed to get it to work on at least the NV17)

- cleans up the DEBUG option (similar to the new radeonfb).  This also
  makes it easy to replace printk by btext_printf() (on ppc) or similar to
  ease debugging of the fb code when all else fails.

- adds backlight control for Apple powerbooks
