What does the output of 'ifconfig mc0' say? (It is an mc0 on
the 7300, no?) Does it appear to be up and configured correctly? 
Do you see any complaints from the kernel about collision errors
or lost carriers ('dmesg | grep mc0')? Or is the problem that the 
interface is not detected by the kernel at all?

If everything looks correct from the point of view of the 
powermacs, it could be that the switch is not properly negotiating
the media type. There are interoperability issues with some
10/100 switches and some ethernet cards. What kind of switch is
it? If possible, try manually setting 10Mb Full or Half Duplex
in the switch config.
