I have tried with vgaswitcheroo on a Vostro 3500, it doesn't work but
is pretty close.

# lspci | grep -i vga
00:02.0 VGA compatible controller: Intel Corporation Arrandale
Integrated Graphics Controller (rev 18)
01:00.0 VGA compatible controller: nVidia Corporation Device 0a75 (rev a2)


# cat /sys/kernel/debug/vgaswitcheroo/switch
0:IGD:+:Pwr:0000:00:02.0
1:DIS: :Pwr:0000:01:00.0

The Intel and Nvidia cards are on. When I try to switch:

#echo DIS > /sys/kernel/debug/vgaswitcheroo/switch

The LVDS turns off! (why? :S), but from a remote login I was able to
check the switching state:

# cat /sys/kernel/debug/vgaswitcheroo/switch
0:IGD: :Off:0000:00:02.0
1:DIS:+:Pwr:0000:01:00.0

I can turn on the intel card again

# echo ON > /sys/kernel/debug/vgaswitcheroo/switch
# cat /sys/kernel/debug/vgaswitcheroo/switch
0:IGD: :Pwr:0000:00:02.0
1:DIS:+:Pwr:0000:01:00.0

But when I try to switch back to the intel card the LVDS panel turns
on (it seems like the power is managed by the intel card), and after a
few seconds the system freezes out.

echo IGD > /sys/kernel/debug/vgaswitcheroo/switch && dmesg > paste_v3300.dat

Here is my dmesg with drm.debug=4 http://pastebin.com/Z5BuPQZG
