Description Sami Farin 2007-09-18 17:12:44 UTC 
xorg-server-1.3.99.0-269-g547ad21 / x86_64
xf86-video-intel-2.1.0-88-gbda3c69

the same software version works in 32bit mode.

when I hacked around and did this, 64bit Xorg starts up:

No, I don't believe this.  If your screen has no visuals, something else is seriously wrong.
