Disaster happens, for those two stations..

Correct. There is a collision, but the clients won't be aware of it..

It won't know who is who of the two and things will behave very odd for
those stations.
To get around this you need to use a vlan per port, and some advanced
connection marking and policy routing on the linux box to route each to
their correct port (vlan). This will work most of the time, but it can
not be 100% guaranteed and will fail if the two stations choose the same
source port while talking to the same destination at the same time..
