802.1q works just fine with FastEther. Just keep in mind that some software
versions or supervisor engines (switches) can support EITHER ISL or dot1q
but not both. The Catalyst 4003's are a good example (dot1q only).

The recommended vlan encapsulation for Fast Ethernet is ISL. I've never
tried using 802.1Q encapsulation with Fast Ethernet interfaces but if it
woks then great. One thing though....the configuration you posted is Ok for
the most part but you need to configure a subinterface for VLAN 1 too so
the
router can route between VLANs using 802.1Q encapsulation.
