No, I know better than to send something after your merge window closes.  I 
have no desire to be flamed even further on this topic.  :)

And come to think of it, adding the enable/disable bits might be good even 
with the patch to make legacy accesses go through type 1, since PCIe BAR 
probing is probably done the same way (I haven't looked) and so we might run 
into the same problems there.

Thanks,
Jesse
