The only thing that doesn't work (and I can't remember now if it has worked in before) is that using dri in XF86Config locks the display (not the machine, ctrl-alt-del will reboot it cleanly). Uncommenting dri makes suspend work ok. This is with XFree86-4.3.0 on a thinkpad r40. Cheers and thanks, Marc.
