I've pushed the workaround upstream. So you should at least have a booting system. Just don't try to use any accelerated video decoding since that would crash the box again.
Cool, so 3.15 will boot normally for me, thanks! \m/ I am able to play games like Batman Arkham Origins (using wine) without crashing, so no issues so far.
My best guess is that the information in the BIOS about the reference frequency is wrong, but without having the hardware here I can't do much else to get UVD working properly.
Everything is working properly for now. What issues could I face because of this workaround?

I wonder if UVD uses the reference clock directly, or if it uses xclk. If it uses xclk, they may explain the problems. Can you post your dmesg output with this patch applied?
My output is the same as Dieter's: [drm] ref: 2700, xclk: 2700
