The patch forwarded below (already ACK'ed by Petr Vandrovec) still
applies and compiles against 2.6.11-rc1-mm1.

Please apply.

Subject: [2.6 patch] proposed FB_MATROX_G Kconfig changes

The current Kconfig entries for the Matrox G cards are quite confusing:

config FB_MATROX_G450
bool "G100/G200/G400/G450/G550 support"
depends on FB_MATROX

config FB_MATROX_G100A
bool "G100/G200/G400 support"
depends on FB_MATROX && !FB_MATROX_G450

The patch below contains:
- remove FB_MATROX_G100{,A} and rename FB_MATROX_G to FB_MATROX_G450
(FB_MATROX_G450 included support from the G100 to the G550, so
I don't see any non-historic reason why to call it G450)
- small update for the FB_MATROX_G Kconfig text

The disadvantage of this patch is, that you can no longer select support
only for the G100-G400 without supporting the G450 and G550. But
compared with the current confusing Kconfig setup, I don't think that's
a big issue.
