This is what you have to do:
In your config, add:

options         ATAPI                   #Enable ATAPI support for IDE bus
options         ATAPI_STATIC
device          wcd0    #IDE CD-ROM

This will compile everything you need for the ATAPI driver in the kernel.
Alternatively, if you want to just be able to load the lkm, ONLY
define options ATAPI.

This got me confused for a while until I looked at the code closely.
Probably should be documented inside LINT.
