I'm having a similar (?same) issue on an ASUS F8Sp laptop with ATI Radeon HD 3650 running Intrepid Alpha 5 64 bit Live CD. On starting the GDM, I get a gray screen with intermittently flashing horizontal lines. Everything seems to be working except the X, because I can hit Shift- Alt-F1 and drop to a fully functional terminal. I'm attaching the xorg log file. The xorg.conf file appears to be completely unconfigured (no drivers or anything in it), although if I try 'X -configure' I get an xorg.conf file that has the radeon driver in it, but it doesn't work either (gray screen etc as above).
