Not having it in GENERIC doesn't mean that. :) We have a lot of machines at work and none of them run GENERIC, but a custom kernel config. We would just add the option to the kernel (just like now we statically compile in things like COMPAT_LINUX which aren't in GENERIC). I think this fear is perhaps a little inflated relative to reality. -- John Baldwin
