did you try to compare your kernel configuration file with the generic one?
there could be something missing. you could also boot the generic kernel and
try using adjustkernel (it's somewhere in the pkgsrc - probably sysutils) to
generate the config file. the generated file may sometimes need your
inspection, but this application helps a lot...
