The fix for this bug should now be included in Lucid, so I'm closing this bug report.
For the other crashes you are experiencing with blender 2.5, this bug report should serve as a model for a new bug report. mistr has written up how to git-bisect mesa in order to find the bad commit at [1] . Our experience with this bug is that once the triggering commit is found, upstream can fix it quickly. Of course it is possible that the crashes with 2.5 are not due to mesa but an ati driver or something else, but that should be clear from the full backtrace. The hangs you are experiencing may be a GPU freeze (see [2]) or a kernel problem. Also in this case, a bisect is usually what is needed to resolve the problem (but possibly of the linux kernel or the ati driver). This should also be reported in a new bug report.
