That was easier than expected. I've got segfaults every single time I emerged mozilla-thunderbird. Both with kernel 2.6.26 as well as 2.6.27. Reverting back to the open source radeonhd driver made this stop. This is a serious issue because you'll get segfaults only if you're lucky. If not lucky, bad machine code could be produced which on Gentoo being source-based is the worst scenario imaginable.
