I compiled firefox 3.5.2 from pkgsrc and started it on this machine running
a custom kernel. The firefox binary dumped core due to a bad system call
in _ksem_init(). Adding options P1003_1B_SEMAPHORE to the kernel config
resolved the issue.

see above

Either remove the P1003_1B_SEMAPHORE option (enabling the code always) or
change things around so userland fails more gracefully, please.
