Bug#275735: xserver-xfree86-dbg: Removing DRI module does not help

[David Decotigny <david.decotigny@free.fr>]

Hi,

Sorry for the big delay. I just powered on my ibook: now I can confirm 
what Frederic noticed. By removing xlibmesa-dri and commenting out 
everything that is related to DRI (and even AGP), it seems to work 
flawlessly. However the "dri" module is still in the list of the X 
config file, and the radeon kernel module is still loaded (as well as 
the AGP GART).

Now that it seems to work, I'm going to re-use the ibook more regularly. 
I'll spend some time one day investigating the problem a little further.

Attached is my XF86 config file.

Thanks A LOT everybody ! I guess the ibook will work intensively during 
the next few days...
