Xorg Problems upgrading to 4.0

[kyuupichan]

Option "NoAccel" in xorg.conf seems to have fixed it as I've now been using X for 20 mins.  2D is noticeably faster than prior kernels; I assume that's a DRI / KMS advantage.

This GPU has only been moderately well supported historically (unsure if the issue was the kernel or X) e.g. once I go into X I cannot return to a text console - the screen goes blank but I can then return to X with Ctrl-Alt-F9.  This continues to be true with Dragonfly 4.0.
