CentOS - Oct 2005 - ATI Radeon 7000 and DRI

OK, so I've got two PCs with Radeon 7000.  One has PCI version of the 
card, and the other has AGP version of the card.

Before update to 4.2, I had DRI enabled on both of them, and it worked 
stable for me (lucky me).  After update to 4.2, the PC with AGP version 
of the card does not load radeon kernel module anymore, and it seems DRI 
related options from xorg.conf file are ignored.  On the PC with PCI 
version of the card radeon module gets loaded and everything still seems 
to work nicely and stable.

I remember some talk about DRI being disabled when Radeon 7000 is 
detected on Alpha (or PPC, not sure), and this being CentOS specific 
modification.  Has this modification by any chance accidentally leaked 
into i386 packages?  Or is this something that came from upstream?

No. I fixed the Radeon 7000 (RV100) for ia64. In HP ia64-boxes the
MC/ILO board integrated adapter is Radeon 7000.

I did fix it myself.

For CentOS-4.2/alpha i did hack it out for more. If i did it right,
it's disabled by default on every Radeon there. It didn't work as is on
my Radeon 9250/PCI at alpha. I did want to avoid people ending up going
thru firstboot just to find out that display/keyboard is hosed after
installation/first boot, so disabling DRI was kind of tradeoff which i
am willing to take.  This can be fixed later on with updates when
netter known what the heck is actually wrong in the updated
xorg-package.

The hacked version for radeon 7000 fix only would be in 4.2-tree
updates/ia64 (i actually forgot toput it there before, so thank you for
remainding me).

One could just comment out all the DRI-options from xorg.conf as this
would efectively disable DRI too. Boot to initlevel 3 if there is no
ssh/remote access to box to fix it.
