Ah, now I see why we moved from using the active configuration earlier. ;-)

My evil plan is revealed!

Doesn't this prevent us from ever using SSC though, as virtually every single PCH machine has HDMI encoders that haven't been masked out through the chicken fuses or VBT?

That wasn't my intent -- the SSC source gets modulated whenever the VBT table says it can, so when the panel uses the SSC source, it will get SSC. Did I mess something up here? Or is it just some interaction with the mode setting code that I didn't get right?
