ATI legacy/UEFI

[Brian West]

I am currently using the ati legacy perpritory drivers on fedora 17 
x86_64.  It is my understanding that the version of xorg that will ship 
with fedora 18 will not be compatable with these drivers.  Is it likely 
that ati will update them? If not is there a way they can still be used 
as the open source 3d acceleration is not that great. I dont run windows 
or daul boot so if i'm forced to buy a new notebook will the uefi issue 
prevent me from installing/running fedora? Thanks in advance for your time
