Xorg Problems upgrading to 4.0

[kyuupichan]

Hi Francois,

I'm happy to report that having just upgraded to current with the radeon updates, that

1) I can now run X without disabling acceleration - in that it hasn't frozen in 20 minutes, and it
used to freeze in just 1 or 2, and
2) Firefox used to die with a failed assertion on sites that tried to play sound for some reason,
that has also stopped happening (without an upgrade in any packages).  Not sure what the cause
of that was, but it only happened on December / early January kernels I think.

Neil.
