I don't think msi can be re-enabled for this part in OpenBSD, the reason it's disabled is that there is a bug in the 82571/2 chips (errata 63 in http://www.intel.co.uk/content/dam/www/public/us/en/documents/specification-updates/82571eb-82572ei-gbe-controller-spec-update.pdf) and the symptom in affected machines is that the card doesn't transmit at all, so unless someone else has a clever idea I think this will need to remain a local patch.
The only other thing I can think of that may possibly help is to see if the bios can be persuaded to assign irqs differently..
