1.5_ALPHA, but I think there is no functional change around sip.

Now I notice there are some syslog massages on other machine:

arp info overwritten for by 00:40:22:6c:54:47
arp info overwritten for by 00:40:06:6c:54:47
arp info overwritten for by 00:00:22:6c:54:47 is the i386 machine with sip, so I guess
there are some timing problem around eeprom code in if_sip.c.
According to dev/ic/i82557.c, it seems one more delay()
is needed:

 				data[i] |= (1 << (x - 1));
 			bus_space_write_4(st, sh, SIP_EROMAR, reg);
+			delay(4);

I'll check how this patch works both on i386 and macppc.
