By the config file.  If you enable the module in the config, it is
built into the kernel, otherwise a kld is generated.

Whether or not a specific feature is capable of operating as a kernel
module or built in is specific to that feature.  Some work very well
in either capacity (the FAT filesystem drivers for example) others
don't really work compiled into the kernel (vinum) and many others
_must_ be compiled into the kernel for them to work correctly (ISA
and PCI support, I believe)

I don't know specifically about ohci, but the man page for ohci would
be the first place to check.
