Does the FOSS radeon driver work with the 7970M (RadeonSI Pitcairn)?
I did a search for the 7970M on the forums, but the only results were the ATI Lounge and a couple other very, very long threads (and the search didn't tell me where in the hundreds of pages the references for the 7970M were), so I figured I'd make a post and ask a direct question:
Does the radeon kernel module (foss driver) support the 7970M?
I've tried activating the radeon driver via vgaswitcheroo (echo DIS > /sys/kernel/debug/vgaswitcheroo/switch) but that just results in a black screen (which I can get out of by echo IGD the same thing).
I've had some moderate success using the fglrx module, but switching is iffy at best, and I've had some very strange results with running dual monitors on fglrx with the 7970m. I'm checking out options for using Bumblebee/Ironhide modified to work with fglrx (http://forums.gentoo.org/viewtopic-t-909802.html) , but before I do that I want to give a go at trying to get the radeon kernel module to play nice with the 7970M.
Thanks for any info!

Cool, thanks.
I see that PXP/Enduro (aka hybrid switching) is MOSTLY marked on the X.org chart -- does anyone have any experience getting the 7xxxM series to successfully switch with vgaswitcheroo? I'm running into a wall here -- whenever I do this
echo DIS > /sys/kernel/debug/vgaswitcheroo/switch
It just gives me a black screen until I switch back to IGD. 
EDIT: I guess, at this time, it's not entirely possible due to limitations in X (which I kind of assumed): https://bugs.freedesktop.org/show_bug.cgi?id=37528
Which likely means that I'd have to do something along the lines of Bumblebee, which I believe has a radeon branch (amd-common)
