Bug Description
Please mark the Mobility 7500 (1002:4c57) blacklisted in compiz. In lucid unfortunately there are some regressions in X for this particular hardware. We're working with upstream to get them sorted out, but I'm losing confidence that we'll have a patch in time for lucid. As a workaround, until a fix is in hand, we need to blacklist the chip from compiz which will help avoid some of the worst of the issues for now.
[Original Report]
In trying workarounds for bug #507148 I disabled KMS by booting with radeon.modeset=0. I had compiz disabled, then enabled it. I had screen garbling so tried to take a screenshot. This worked but after double clicking on the Screenshot.png on my desktop, X froze. I could ssh in, so I ran 'ubuntu-bug xorg' from there. I do not have an xorg.conf file.

Hmm, this sounds awfully familiar. What was the dimensions on the png?
There was once a bug where if you loaded a png with dimensions equal to or larger than the screen resolution, it'd trigger an array bounds issue. Does this bug reproduce reliably when loading the png? (Try loading it in firefox too - iirc the bug also triggered there.)
