Hi Jerry,
As far as I understand from your post, FastEthernet0 and VLAN1 are in different subnets, and in different vlans.
In this case this should cause no problems to have the same mac-address on different interfaces.
Multilayer switches regularly use the same mac-address on different vlan interfaces.
A layer2 address is used only within the boundaries of that layer2 domain.
Cheers:
