The ASA5510-BUN-K9 for the ASA5510 includes 3 Fast Ethernet interfaces, stateful firewall, 250 IPsec VPN peers, 2 SSL VPN peers, 3DES/AES license, and 1 expansion slot, this should be sufficient to enable IPSEC on the Chassis and configure it to work.
I hope you can post the configurations and "deb cry is" and "deb crypto ipsec" outputs from the ASA when you have issues bringing up the tunnel.
