With this change, they definitely fix something because I even get X on

start X with the login window. And my suspicion is that wdm (WINGs
display manager) I'm using, does /dev/mem accesses when it starts and it
obviously failed. Now not so much :-)

That's crazy. Didn't expect that at all.

I guess X is happier getting an error than getting random pages back.
I'm working on a set of patches now that should get it _working_ instead
of just returning an error.

Awesome :)
