The attached patch adds a new option to the PCI code (options 
PCI_MAP_FIXUP) which enables code that does lazy allocation for 
memory/ioport resources in pci_alloc_resource(), and adds and allocates 
certain resources for PCI ATA controllers in legacy mode in 
pci_add_resources(). These resources are missing from the BARs, and as 
it's part of the PCI spec as special case [1], it should go here. The 
code comes from FreeBSD, who reasoned the same [2].
I think the lazy allocation is nice, but the ata part, I still don't like.  Yet, I agree we should have it better hackish than not at all.  Cleanup can come later...

cheers
