It seems ok to kldload sbp after the system is up, ie the machine doesn't panic, but I don't have anything firewire to test with. Would it be an option to have sbp disabled by default in the install CD's? Those without the problem can put sbp_load in loader.conf, those with the problem will have to kldload it later but at least they will be able to install.
