in some cases we actually have to allocate the BARs and so on and
leave it disabled -- we don't know if the OS wants it, but if the OS
wants it, it has to work. This is one of the less intuitive bits of
the device bringup process.

yep, we actually have to set up the BARs even if it is not enabled in
the tree. We can't leave the OS in a situtation where it can't use the
device.

thanks
