Subject: [PATCH 0/2] x86: add function to check whether BIOS NX and let
 uvesafb work

hi,
https://lkml.org/lkml/2011/11/17/54 is the first time I
post the question I meet.At that time, I haven't idea to 
catch it bug! My computer hang too early, and even seral 
console doesn't help.
Recent days I try to compile uvesafb as a module, and insert 
it when I have a full work kernel, X11, and sshd. Good dog,
the bug occurs again, and I catch it!
Here are the two patches that I try to fix it,
I will appreciate for any comments.Thanks

attached patches:
1/2 x86:add function to check BIOS whether NX
2/2 video:uvesafb: check whether BIOS is NX before try to use PMI
