I have the same symptoms on an Asus L3T laptop (sis650 video card) with 2.6.20-5 (also on -3 and -4) on feisty. gdm starts, and after 2/3 seconds it freeze, corrupting the graphic; switching to console and back gdm (ctrl-alt-f1 and alt-f7) restart to work. Also killing gdm with crtl-alt-backspace works.
