Some very, very old devices don't exist as modules.
This SCSI controllers (ISA-only?). I just drop this.

device         adv             # Advansys SCSI adapters
device         adw             # Advansys wide SCSI adapters
device         aic             # Adaptec 15[012]x SCSI adapters, AIC-6[23]60.
device         bt              # Buslogic/Mylex MultiMaster SCSI adapters

This 10Mbit network cards. I just drop this.

device         cs              # Crystal Semiconductor CS89x0 NIC
device         ex              # Intel EtherExpress Pro/10 and Pro/10+
device         ep              # Etherlink III based cards
device         fe              # Fujitsu MB8696x based cards
device         xe              # Xircom pccard Ethernet

I attached my kernel config.

My loader.conf. Not all modules from GENERIC present. I can write
loader.conf with full list of modules from GENERIC kernel.
