2.6.15-rc2-git4 on Dell D610 - PCI resource allocation failure

[Alessandro Suardi]

Another one from the new Latitude D610... both the latest FC4
 kernel and 2.6.15-rc2-git4 fail to allocate PCI resources - not
 sure whether FC4 also gets the "Ignore bogus resource" one
 which is here taken from the 2.6.15-rc2-git4 dmesg ring:

[17179572.144000] PCI: Ignore bogus resource 6 [0:0] of 0000:00:02.0
[17179572.144000] PCI: Failed to allocate I/O resource #7:1000@10000
