Hi Nathael, your driver seems to be the most complete framebufferdriver for this chip I heard about :-)
Our driver is currently based on some register dumps by SMI. The chip is completely setup by U-Boot. Because of it's missing generic'ness I did not dare to post it as a patch to the U-Boot list :-) Finally we are using a stupid framebuffer driver that does absolutely no 722 setup. It just represents the framebuffer driver interface. I will give your driver a try.
