After some more experimenting, and using tulip-diag -fa to examine the
value of CSR9, it appears that the top 4 bits of CSR9 are set to zero
under some circumstances.  This seems to happen when
disconnecting/reconnecting to test autonegotiation.  Typically, a
message of the form:

    eth0: PNIC transmit timed out, [...], resetting ...

is output to the console.  Are there other locations where CSR9 should
be reloaded?
