Okay; Now, on X40 I have resolved the issues as follows:
1. Add "video" to /etc/modprobe.d/blacklist 2. Add "brightness_mode=2" after "fan_control=1" in /etc/modprobe.d/thinkpad_acpi.modprobe After these steps (and no other, the nmi_watchdog and acpi_sleep options are no longer necessary in grub's menu.lst as kernel parameters; in fact, no special kernel parameters are necessary; neither is fiddling with PipeA Options in xorg.conf), I no longer have my notebook hanging during shutdown or video change. Which is what I was ultimately aiming for :) Try these things for yourself (namely, the video).
