Ick, no, not another kernel boot parameter.  I would prefer the /proc/
file solution instead, just like /proc/sys/kernel/hotplug is.

But, that really wouldn't work for boot time, so, again just like
hotplug works, make it also a Kconfig option for those distros that
build their own kernels and keep their firmware in odd places, or don't
have a /lib/ directory, can override it easily.

thanks,
