[PARISC] lba_pci: pci_claim_resources disabled expansion roms
Kyle McMartin [Thu, 6 Dec 2007 17:38:26 +0000 (09:38 -0800)]
radeonfb was HPMC-ing my C8000 by trying to map its expansion rom from
IO_VIEW, instead of PA_VIEW. Fix seems to be to ensure that its disabled
ROM is properly inserted into the resource tree.

FIXME: this will result in a whinging printk for cards which share expansion
ROMS, such as a quad tulip. Thankfully, it isn't harmful.
