"Excessive collisions", i.e. 15 collisions in a row when trying to transmit
a packet? Your network must be heavily overloaded.
Anyway, the messages are output inside the kernel to the console device.
You could use a serial console or write a program that redirects the console
to a pty and logs the output..

For most Ethernet cards Suns adhere to the original Ethernet spec that
all Ethernet cards in a machine should have the same Ethernet address.
