that makes it worse
If you want to put a device specific sysctl/ioctl set out there then 
have a device INDEPENDENT
tool that knows how to handle the devices we have modified and when we 
have  enough examples we can change the
ioctl/sysctl interface to a generic one without changing the interface 
people are using in their scripts.
