For the record in this bug, this was my revert:
commit e1b2d424de27643a2ff2ccdca4a187b083c1b389
Author: Loic Minier <[EMAIL PROTECTED]>
Date: Wed Oct 10 20:57:55 2007 +0200
Revert "Revert "Revert "UBUNTU: remove broken changes from intel-agp.c"""
This reverts commit a14a5742c371dc55ca55bfc23bec892dfea26b9b.
Causes major corruption with the xserver-xorg-video-intel fix in place.
(so a revert of revert of revert of removal :-)
In the end, what I wanted is to flip the seemingly only change related to G33
between -13 and -14, which resulted in using the current upstream code and in
this diff:
