The simple things in life

I've spent a while trying to make GPU switching work more reliably on Apple hardware, and got to the point where my Retina MBP now comes up with X running on Intel regardless of what the firmware wanted to do (test patches here. But in the process I'd introduced an additional GPU switch which added another layer of flicker to the boot process. I spent some time staring at driver code and poking registers trying to figure out how I could let i915 probe EDID from the panel without switching the display over and made no progress at all.
And then I realised that nouveau already has all the information that i915 wants, and maybe we could just have the Switcheroo code hand that over instead of forcing i915 to probe again. Sigh.

Apologies for the offtopic reply [wireless/b43 related]

Or did you have this problem, and manage to work around it? Google reveals very little information; I suspect that's because so few people are using Linux on this model laptop.
Thanks for your help - I love reading your posts, particularly ones that help Apple hardware (why do I have this blasted laptop again?).

Being able to switch like Matthew is working towards is the holy grail I guess. But for me switching to radeon has made the machine very effective running Debian. (I used to use the intel graphics card but it would go all black on suspend/resume, which something I really want to be able to do)
