I'm utterly confused by this. This is basically saying we should try to probe for an extended device space for every host bridge. Logically speaking, this is valid: if there is a valid path by which we can probe for byte 256 then it should succeed.
HOWEVER, the same argument applies for *every single device*. So if this does indeed work, why should we limit it to host bridges?
