OK, you are the one who must be better aware of the whole picture, so  
if the intention is to make the resource busy, that's my first patch  
and whatever you are trying to push.

You still may want to have a look at my second patch that widens the  
resource to match an appropriate PCI BAR.

I'm too puzzled why the resource conflict warning causes a GPU lockup  
for another user.  Maybe it's an unrelated issue.  Also, I don't use  
UEFI.  I plan to test it eventually if I figure out how to migrate to  
it without reinstalling everything.
