Yes, the default AGPmode changed (again) recently. And actually it is
now back to the same behavior than in the old 6.6.x days. IIRC, by
default, it just tries to use the BIOS mode. If this default mode
doesn't work, you need to either change your BIOS config or use AGPMode
in xorg.conf.
The developers have been looking for a sane default for a while. But,
both the new and the previous behaviors cause some freeze on some
machines. They don't know how to do anything better unfortunately...
