Here's an updated version of the patch, which should work on more cards. Specifically, it works on my rv250, rv280 and 9100igp should probably work too. Not so sure about r200, only if you're lucky...
I had to revert this line, to see something (r200):

Basically, this is is the test that chooses between doing a fast zclear and a standard zclear.
But you don't want to do both.
That was a mistake in my first patch. The second one has this change.
Now, I have 'only' the black lines (gears, gloss, etc.). But isosurf it mostly fine?! --- Depth??? See isosurface1.
But if the 3D window is vertically to high or if I move a small window to the bottom of the screen, then there is additional pixel (texture) corruption.
See isosurface2
Same problem as the last one, I think.
Some things are still broken, notably apps which use stencil buffer (nwn, doomIII). I think there could be an issue when clearing stencil or z-buffer separately, or maybe something else (dinoshade at least seems to work).
Here, too.
But I saw something semilar (depth corruption?) with viewperf before HyperZ.
Also, if another window is moved on top of the glxgears window so it covers part of the glxgears window then rendering is very broken - mostly just black, that seriously seems to break z buffer clearing.
Nothing, here. (With my change).
That's because only the first box is cleared. This can be easily fixed.
