Elbox's Eflash product would come in handy (at least for A3000/A4000 owners) in order to pre-load all mediator drivers at boot and allow you to practically autoboot from the PCI IDE controller, however it doesn't look like Elbox will make use of this idea as it's been quite a while since Eflash was released and no new, or should I say useful stuff has come out for it.
