I'm not aware of one, but I can suggest a few pointers... Drivers are easy, turn off what you don't need. Under "general setup" and "processor type and features", anything that isn't for your particular CPU (ie: AMD options for an Intel CPU)... You can go further than this but then you start getting into stuff like enabling/disabling crypto groups and networking options (like netfilter/iptables), which is probably fine as is.
Cheers

Note
It is a common misconception that genkernel will "automatically" generate a custom kernel configuration. genkernel automates the kernel build process and assembles the initramfs, but does not generate a custom kernel configuration file. It uses a generic kernel configuration file that provides support for commonly used subsystems on an architecture-specific basis. Details on the architecture defaults can be seen in the upstream repository. Select the architecture and then choose the kernel config file. |
You can try Sakaki's Configuring_and_Building_the_Kerne guide.
But here, too, technical understanding is required.

InvisibleRasta,
There is a guide from 2005
The process is still valid.
pappy_mcfae took it further.
While that site is no longer maintained, pappy_mcfae still provides updated seed .config files Pappy's preconfigs! so that method is still supported.
Lastly there are some minimal default configurations provided in the kernel.
They all come back to lots of coffee and lots of reading.
