Hi :-)

I'm trying to get vga_switcheroo to work to switch between integrated Intel and
ATI Radeon graphics. Intel is set to primary display ('init display first') in
BIOS. The radeon driver appears to not like this:


[    3.464108] [drm] radeon defaulting to kernel modesetting.
[    3.464110] [drm] radeon kernel modesetting enabled.

When I disable the Intel card it works fine. The radeon card is a HD 5450, by
the way.

I have attached dmesg, uname -a, and lspci.

(This is my first bug report on kernel.org so please be gentle ;-))

Thanks for anything you can do :-)
