mods for the ultra40 bringup. This now builds.

amd gx2 north -- don't set anything in the north, it conflicts with vsa
settings. So we have our own pci_set_resources that is essentially a
no-op -- just calls the kids. 

olpc rev_a config -- DISABLE the compressed rom stream. This SHOULD NOT
have been set -- it is untested and caused real trouble.
