kernel config file

[Fbsd8]

Back around 4.x there was a File that had all the available kernel 
compile options with their meanings as comments. On 9.1 I don't see that 
file any more. Where can I find that file that lists all the kernel 
compile options? The 9.1 NOTES file is not that file.

I have "makeoptions NO_MODULES=yes" statement in my kernel config file 
and the "blanktime" and "warp_saver" load modules don't get created.

I need the options statements for those items so I can compile then into 
the kernel.

Thanks
