To add your driver you update the src/sys/conf/files* files.  If your driver 
is machine independent, you can add it to src/sys/conf/files.  For example, 
here are the lines in sys/conf/files for the cy(4) driver:

dev/cy/cy.c                     optional cy
dev/cy/cy_isa.c                 optional cy isa
dev/cy/cy_pci.c                 optional cy pci

If your driver only works on a single architecture (such as i386) then add it 
to the architecture file sys/conf/files.<arch> (e.g. sys/conf/files.i386).  
The device names after 'optional' specify which devices must be enabled in 
the kernel config for that file to be included.  Thus, in the example above, 
src/sys/dev/cy/cy.c is included as long as 'device cy' is in the kernel, but 
src/sys/dev/cy/cy_isa.c is only included if both 'device cy' and 'device isa' 
are in the kernel config file.
