Hi Oles,

I'm not sure how to specify which modules not to build, but to build 
only the modules you need, use MODULES_OVERRIDE in your kernel config 
file. E.g. the following line will build and install only atapicam and 
ext2fs.

makeoptions MODULES_OVERRIDE="atapicam ext2fs"

To find out what modules you use, just type kldstat in the console, and 
add the listed modules to the MODULES_OVERRIDE.

You can also specify that you don't want debug symbols built by removing 
or commenting out the makeoptions DEBUG=-g line.
