e1000e kernel module (unknown symbol in module)

I'm running into issues building a new kernel module in support of the I219-V.

Initially built with driver v3.3.3 against kernel 3.0.13-0.27-default. The module (e1000e.ko) loaded without issue, but the environment lacked USB support for the target devices (no mouse/keyboard).

I rebuilt with driver v3.3.3 against kernel 3.0.76-0.11-default. Mouse/keyboard work now, but the e1000e module does not load. It's being loaded by insmod, which reports:

     insmod: error inserting '/modules/e1000e_3.3.3.ko' : -1 Unknown symbol in module

I also tried with driver v3.2.7.1 against the same kernel (3.0.76-0.11-default) -- same behaviour.

Is there a trick to building the e1000e module against the (slightly) newer 3.0 kernel?

Thanks!
