nForce2 with 2.6.3-rc3-mm1 : oops when X started

[Niraj Kumar <niraj17@iitbombay.org>]

Hi,

I have am ASUS A7N8X-VM with Athlon 2000+ .
I got this oops just after a few seconds after starting X . The display 
freezes although mouse continue to move . I was able to press 
<ctrl-alt-backspace> to come back to text mode.

I have heard that 2.6.3-rc3-mm1 has got some fix for nForce2/AMD
hangup problems . Is that right ?
