I programmed a static DHCP-entry on my local DHCP-server so I would
notice if the MAC address changes. Just turned the computer back on and
received the intended IP address, so the MAC address seems to stay the
same with the vendor driver.

The vendor part of my MAC is 6e:69:73 which is interesting because
according to some Vendor-Lookup-pages the vendor is unknown.

Karsten
