OK, I've been trying for hours now to get the most out of my ThinkPad T42's GPU in 12.04, but to no avail. I finally got dynpm running for power management (sometimes jumpy, but OK), but I can't for the life of me figure out how to get AGP 4x turned on. I'm used to working in Xorg.conf and have NO idea how to do any of this KMS stuff... HELP!!!
