new pro/1000MT not detected

I recently bought an Intel PRO/1000MT (PWLA8492MTBLK5) dual port 
adapter which,
according to em(4), should work with 3.4-RELEASE.  The dmesg shows that 
the card is not detected:

vendor "Intel", unknown product 0x1079 (class network subclass 
ethernet, rev 0x03) at pci0 dev 15 function 0 not configured
vendor "Intel", unknown product 0x1079 (class network subclass 
ethernet, rev 0x03) at pci0 dev 15 function 1 not configured

I wonder if Intel has made a new chip for the pro/1000MT adapters.  
Looks like FreeBSD does support the chip on this adapter so maybe the 
drivers need to be updated on OpenBSD?  Anyone else have the same 
problems?
