Are there any workarounds? The only other driver I can use would be this Nouveau one I heard about on freebsd-x11, but that would involve another system upgrade, and it is currently marked as broken.

There's probably not enough information to pinpoint a version, but would downgrading to Xserver 1.4.2 (or an even older version) work? Or, alternately, is there an ETA on the switch to libpciaccess? Do you know in which version the libpciaccess changes were introduced?
