What is this code trying to do anyway?  It looks like it's checking for 
overflow and trying to make sure that the offset is in I/O space?  Are those 
checks really necessary?

It also looks like drm_addbufs_pci uses virt_to_bus, which won't work on many 
non-x86 platforms.  Hmm... the version in latest 2.6 kernel tree doesn't seem 
to have these problems, which one is the master copy?
