 you can use userconf from /boot and boot.cfg.  that sounds
 like the only way to handle this today.
 
 41780 is likely never solveable.  boot -c needs to operate
 before any devices are configured, and usb kbd without legacy
 emulation absolutely needs devices configured and sort of
 running, before it can really work properly.
 
 ideally, multiple console devices would solve 53599, and there
 is some work in -current to begin to support it.
