The problem appeared when I merged radeon driver fixes by Kevin E. Martin from XFree86 CVS to DRI CVS. They involved adding new fields to the XaaInfoRec struct; the fact that they were added in the middle of that struct caused the DRI binary snapshots, which were built against the new version of that struct but ran with an XAA module built against the old version, to crash and burn. I moved the new fields to the end of the struct, bumped the minor XAA version and added code to the radeon driver to only access the new fields if it's dealing with the new XAA. That worked as expected when I tested it here by copying libxaa.a from my Debian 4.2 installation into my DRI tree, which makes me suspect that the remaining problem with the snapshots is due to toolchain incompatibilities or something along those lines.
