Have you actually tried eepro100 on Alpha? Because I am trying to get
eepro100 to work on my IA64 platform and it fails because in
speedo_start_xmit gets an skb that is at > 4Gb... and the card is only 32
bit, so it fails to send!

Best Wishes,

Sure you can (eepro100), but not all drivers are aware of 64bit
