They're wired to the board.  I'd probably break the connector if I remove
it.  This box has custom hardware attached, I don't expect any of the
drivers to attach (with exception of the std onboard ethernet) because
of this.  I do want -current to come up so I can begin driver twiddling.

I found some and turned on bios ecc logging.  Same panic, no ECC errors
corrections.

Based on my later replies - October 16th boots fine, and October 17th
snapshot b0rks on this panic, I'm not convinced the em driver is at fault.
I will recompile w/o em in the kernel to test this theory.
