[PATCH] G550 config entry/help

[Robert Love]

I was confused how to get the framebuffer working on my Matrox G550
until Dave Jones kindly pointed out that the G450 driver works. 
Additionally, there are other issues wrt to the second head and analog
output that should be documented.

The attached patch, which applies to 2.4.17-rc2 and 2.5.2-pre1, updates
the configure entry and help appropriately.  Linus and Marcelo, please
apply.
