just to complete the description of the scenario, this is booting from a physical CD-R with an .iso file built using jam -q -j5 @alpha-cd (x86gcc2hybrid).....

just as added info, it seems the gPCI reference in pci_get_msi_count is NULL, while the x86 pci module that it is in seems to be properly loaded, and that does a get_module() on the main PCI module from the module init routine. I guess there's something subtle going wrong there, but I don't have the time to look into it right now (want to get further with the ARM port first ;))
