2440: Update Intel NIC firmware?

[mwp821]

I recently updated the Intel NIC firmware in another FreeBSD machine so I thought I'd do my 2440 as well. So here I am a few hours later, still trying to figure out how to do it. As far as I can tell, there's no way to boot into an EFI shell to run the BootUtil program, which seems to be the only way to apply the firmware update. Thoughts?
