Benjamin,
I faintly remember adding code to the Xserver that it wouldn't do this
when you only used fbdev drivers.
It may do this for setup (ie. probing) as it has no idea about the drivers
it is going to encounter. With the new interface I've added we may actually
change this. I'm already doing this to determine if I need to enable PIO.
I need to look at this code again, though.
Egbert.
