I tested your module on my Asus N53Jf with ubuntu 10.10 and 2.6.38. It seems to be working right now, although it gets me a little confused.
echoing ON and OFF impacted battery drain rate as expected, so I guess discrete GPU is shut down properly. Then I tried to switch to discrete. I echoed DDIS, then tried an X restart with Alt+sys+K (Ctrl-Alt-Bckspc doesn't work for a reason..). This gave me a blank screen I could not leave. I noticed that the screen was lit though. On reboot, I had a blank screen between GRUB and GDM, so I assume I was on discrete. This time the screen was not even lit, it was completely off. Now, what confuses me is the output of cat /sys/kernel/debug/vgaswitcheroo/switch wich says : 0:DIS: :Off:0000:01:00.0 1:IGD:+:Pwr:0000:00:02.0 But I noticed echo OFF no longer lowers battery drain. Rate stays at ~30W, which is a typical rate when GPU is ON. Is the cat command unreliable ? Or do I misunderstand it? I don't really have use of the discrete card, but the good news for me is I don't get frozen on shutdown anymore with the xorg cold bug. May be related to the new kernel tough, as I was running under 2.6.35 and updated to test this module. Good work anyway.
