Not that it's at all relevant to the question here, but...
It does mostly work without em in the 12 kernel - I'm not sure how, but
it does.
I upgraded to 12-stable via source but didn't add em to my custom
kernel. Most things worked - basic network functionality. But I had
problems with ipfw and igb. Adding em to the kernel fixed them.

Something odd going on there there - I am using 12-STABLE and I have
igb just fine, and it attaches to the same hardware that 11 did:
It does work in 12, throughput is great, just that the latency is
higher than 11.

Do you have a custom kernel, and if so did you see this note in
UPDATING?
Yes I do, but it includes all of GENERIC which includes em drivers,
otherwise it wouldn't even work with the network card.
my custom kernel:
include GENERIC
ident CUSTOM
makeoptions WITH_EXTRA_TCP_STACKS=1
options TCPHPTS
options SC_KERNEL_CONS_ATTR=(FG_GREEN|BG_BLACK)
options IPSTEALTH
options AHC_REG_PRETTY_PRINT # Print register bitfields in debug
options AHD_REG_PRETTY_PRINT # Print register bitfields in debug
device cryptodev
device aesni
I did try without RACK just in case that was the culprit.
