Actually, the commits that I might have expected to cause this, haven't
been MFC'd yet. You probably did pick up the r6/7xx code in this
update. I also made an error in the GART mapping code, but that should
only effect pci(e) based radeons.
It could also be related to the 6.12.1 ati driver. AGP mode 4x is
always suspect as well, you might try reducing that to 2 or 1 and see if
the problems go away.
As for checking out an earlier release, with csup you just have to
specify a date that you want to checkout. See man csup and reference
the section titled CHECKOUT MODE.
