Hi!
I've tested on two different computers, my ThinkPad x230 and my desktop 
with a Intel DQ77MK motherboard.  I've only done light testing such as 
loading efirt.ko and running efibootmgr to check the boot settings, but 
it has worked fine.
I also haven't seen any issues with console graphics on either machine.
Both computers are running CURRENT from yesterday, the desktop is on 
r331481 and the laptop probably somewhere around that as well.

Please let me know if you want me to test anything else!
Regards
