Hi Gerd,

just took a quick look over this and it seems in pretty good shape,
the one worry I have is if you've tested with vesafb loaded, since you
do some pci_request_regions and fail hard, if vesafb has some of the
resources this can end up failing the driver load for no good reason.
I haven't verified there is a problem here its just something we've
had in the past.

Dave.
