It's not exciting perhaps but it does work quite well for me (unlike earlier versions). Suspend/resume works now, the "Unsupported hardware" watermark that I briefly encountered with 12.6 is gone again and the performance problems with vblank seems to be fixed.
I've had two segfaults since updating (colord and compiz) but I'm not sure if that's related to fglrx.
Oh wait, that's because I'm using the superior free radeon driver and not some crappy blob.
Yeah the free driver does work perfectly fine on this machine (AMD Brazos C-50 APU) in terms of suspending etc but on the downside the machine runs about 10 degrees celsius hotter and HD videos don't work without skipping and pauses whether the blob works fine there and has better power management.
I know the C-50 isn't the most powerful or modern Fusion APU though, I don't know whether suspend and resume will ever work.
