[coreboot] Lenovo G505S blob status?

Is it possible to init the graphics device without the radeon bios blob? 
such as with openradeonbios or with linux (you could do a petietboot 
solution to get graphics pre-OS)

It has no PSP (or obvs ME) and its performance is about equal to a sandy 
bridge, so it seems like a great choice if you don't need the dock 
connector on a pro series thinkpad like the t430.

AFAIK that version agesa is open source, at least I looked at it and 
didn't see anything weird but I am not an expert on this.

- Thanks
