This still has a build error when CONFIG_PCI=n:


linux-next-20081229/drivers/scsi/fcoe/fc_transport_fcoe.c: In function 'fcoe_load_transport_driver':
linux-next-20081229/drivers/scsi/fcoe/fc_transport_fcoe.c:324: error: 'pci_bus_type' undeclared (first use in this function)
make[4]: *** [drivers/scsi/fcoe/fc_transport_fcoe.o] Error 1
