Just noticed this issue still occurred with Mesa-7.11 (even on real Cirrus HW)
Checking the source, I found that the patch from comment 5 was missing.
Applying the patch, fixed glxgears,
but left other programs (e.g. KDE4's khelpcenter and konqueror (both using
KHTML)) with similar bpp corruptions in image rendering, which are not present
with other drivers.

Hi Brian!

I have done these tests:
* without my patch : 
 * qemu + cirrus emulation + glxgears - failed
 * qemu + vga emulation + glxgears - working fine
* with my patch
 * qemu + cirrus emulation - working
 * qemu + vga emulation - still working fine

So it seems that this patch solves the problem, and does not introduce
another bug.

So I'm confident in this patch ;)

Regards

OK, I've cherry-picked this to 7.11.

The patch was committed to master as commit

How confident are you in the patch?  Should it go into the 7.11 release?

Mesa-7.10 swrast on Qemu/KVM's emulated 24bit cirrus graphics is still broken.
Looks like this:
http://openqa.opensuse.org/opensuse/permanent/bug/bfo23525.png

but works on vesa driver that has
(II) VESA(0): Creating default Display subsection in Screen section
Default Screen for depth/fbbpp 24/24
(==) VESA(0): Depth 24, (==) framebuffer bpp 24
...
(==) Depth 24 pixmap format is 32 bpp

and also works on fbdev with 16/16
