AFAIK the announced breakeage concerned C++ only. >Since very few people seem to have GCC 3.2 at the moment (I do have a >Gentoo 1.4-pre1 box that does, but haven't tried DRI snaps on it yet), >can we please have some built with the old gcc?

The ability of gcc-3.2 to generate more efficient code to Pentium III and IV, being able to generate SSE and SSE2 instructions automatically was one of the main reasons why I installed Redhat beta, since I do lot of numerical stuff. This together with the new gnome2 desktop. Unfortunately I don't have other machine were I can build those snapshots, and SourceForge compiler farm fails to build the snapshots except for some cards (ATI cards IIRC) due to an outdate Xfree installed on the system. RedHat does indeed provides a compat-gcc package. I'll see what I can do to use it within my scripts. Nevertheless it would be good to be sure about these binary compatabilities, since the widespread of gcc-3.2 will happen very soon.
