Gereon,
You can count on getmac.exe utility ("Server Command Line Tools" component)
and satisfy its dependencies. Although I don't think it is a smal piece.
Also, ipconfig /all will return the MAC addresses of all the installed NICs.
You can certainly use GetAdaptersInfo API to the the MAC address. You would
need TCP/IP stack and IP Helper stuff included in the image.
Or use SendARP API. Something like this:

Going "deeper" you could use NetBIOS (NetWkstaTransportEnum API) to get the
MAC. But it still requires the NETBIOS stack to be installed (and TCP/IP).
Another low level approach would be quering NDIS miniport driver with
OID_802_3_CURRENT_ADDRESS
(http://msdn.microsoft.com/library/default.asp?url=/library/en-us/network/hh/network/23ethoid_e5a532d2-8b51-4a68-ab05-19fb86825b15.xml.asp).
