What Scyld version?  Which driver?
The usual problem is forgetting to click 'apply', but you seem to know
about that.

One possible problem with older releases: if you have certain specific
3Com cards the driver may not have reset the transceiver correctly which
results in Tx but no Rx.  But this is rare...

A neat trick for a single NIC in the master is to use IP aliasing.
Install with "eth0" as the external interface, and "eth0:0" talking to
the cluster.
