Good point, how about:
	People like running their machines with thousands of raw
	devices, yet distros don't want to take up that much memory for
	all users.  Provide a way for everyone to be happy without
	forcing the module to be rebuilt by providing the ability to
	specify the number of raw devices as a module parameter option.

thanks,
