Hi Guillaume,

I tried the same thing on my UL30VT running Fedora 13 with 2.6.35 RC6 kernel
(2.6.35-0.57.rc6.git1.fc14.x86_64). The nvidia card actually still appears
with lspci,
and there is no difference in power usage (using powertop for monitoring).
It seems like the card is not turned off when using switcheroo...

I noticed another thing: when I disable the nvidia card using switcheroo,
and then
I turn my laptop to sleep using Fn+F1, the system hangs, the cpu fan speeds
up,
and all I'm able to do is turn it off manually with the power button.

I'll continue to test vgaswitcheroo of newer kernel release, but I'll keep
the
nvidia_g210m_acpi module loaded the rest of the time :)
