I think there's some confusion between VLAN (802.1q or ISL) and MPLS
VPN.  It sounds like you really want to do 802.1q or ISL (probably the 
former) with the IBM box, rather than sending it packets with MPLS
labels, which would require the IBM box to have something lie an
rfc2547 implementation.  I don't know if the 390 does 802.1q or not;
best you hear from IBM.....
