Anyone using the free VBIOS implemention for AMD GPUs?

Is someone here using the free VBIOS implementation for AMD PCIe GPUs? Does digital Video output also work on some cards or just VGA(D-sub)?

I have a 5450 (listed as tested working by him) and I am willing to test 
this if you can find me the location (on the card) of the BIOS EEPROM 
just in case anything goes wrong.

I am not sure what other cards are compatible, although the author says 
that anything AtomBIOS probably is (but I am not sure which cards use 
AtomBIOS)

He also says that the other outputs (non-VGA) are initialized by the 
linux kernel but not before that (I suggest using a kexec boot system 
such as petietboot so that you have video output during the boot process)
