Hi!

This "fix" (albeit the bug is in the fglrx driver?) fixes several games for me.
Half-Life 2, Portal, Civilization 5 are now playable. Before:

- Half-Life 2 hanged whenever I went underwater (unless I had set
r_drawwaterrefraction 0). Also I got severe fps boost at some parts of the game
with the fix.
- Portal hanged at the sight of the very first portal
- Civilization 5 crashed when the map was supposed to be shown

Even thought the issues above are different than the bug report, the proposed
fix fixes _them_. So there might be several issues actually discussed in this
bug...

Now all the above games are playable. I still get "flickering" when multi-core
rendering is enabled (it's difficult to describe... as if parts of the world
jump out in wrong shape and / or are only partially drawn and become absent /
totally transparent). If I have multi-core rendering disabled at startup, I
also get the flickering at a slighter level, but it is gone totally once I
enable multicore rendering (go to the main menu in between) and then disable it
again right after.


Hope this helps some users wathing this bug,

 - Ville
