--- Comment #55 from Forrest Loomis cybercyst@gmail.com 2008-06-26 14:01:31 --- Created an attachment (id=14372) --> (http://bugs.winehq.org/attachment.cgi?id=14372) makes 3d work with the fglrx driver
I finally bisected the libGL drmMap error to this commit: 195ca1e85f01ac40695fbb6fcf9e9e130265f091
So you can run git revert 195ca1e85f01ac40695fbb6fcf9e9e130265f091 and recompile wine to get 3d going, or you can use this patch to revert those changes.
As far as I can tell, everything else is still working under wine (all the programs I use) and 3d is working again!
I have a M76 - Radeon Mobility HD2600 with the Catalyst 8.6 (fglrx 8.50.3) driver installed. World of Warcraft now runs very very well, as does various 3d demos I've grabbed off the net.
So apply the patch (or revert that commit) and say if it fixes it for you!
