With the latest changes to drm in r300_driver I was reminded of a few problems with R420 cards and the r300 driver.

1) the Xorg driver defaults to R200 for R420 cards.
RADEONDRIKernelInit() in radeon_dri.c

2) RADEONInitDispBandwidth() is disabled for r420 cards.
I have no problem enabling this. are there a reason for this?

3) I can enable more pipes for r420 cards, but am unable to test it on 420 cards with fewer pipes.
Do I just add this and wait for someone to complain?



Regarding Xorg are there an easy way to make a diff without needing a duplicate tree? And where should I send the Xorg patches?
