Overclocking and FreeBSD often don't mix.

The most likely scenario I can think of here is that the fourth rl(4) card
is not in a bus-master capable slot. Many motherboards have such a
limitation in that only a finite number of slots are connected to the
PCI bus arbiter with the necessary signalling in place for bus mastering.

The rl(4) driver should share interrupts without problems, as it isn't
marked as INTR_FAST, but it's entirely possible there is a PCI routing
problem with your BIOS.

I'd suggest using a tool such as pirtool to check what the PCI routing
is (available from my website):

..although much of this information should be printed if you boot
FreeBSD in bootverbose mode (boot -v at the loader's 'ok' prompt).
