Both your network interfaces are on the same subnet.  This will not work
as you expect.

The system routing table sees hme1 as the -only- path to 192.168.0.0/24.

Right because the system is ignoring packets to that IP address on that
interface because it sees them as "martian" packets.  There's no way
that packets destined for that IP address can arrive on that port
because the other port is (according to the route table)  the only route
to that subnet, and the subnet is directly connected.

Something that -might- work is setting the netmask for hme0 to ffffffff,
but I think I should ask why you'd want two ports on the same IP subnet.
