	Does anyone know if you can use the revisions marked on the chips
	to identify problem versions? If so, can people report known
	good/bad revisions for addition to the NetBSD/sun3 FAQ.

	I've just added an entry:

Some of the older LANCE chips used in the sun3 (not the sun3x) have
a bug for which the workaround prevents use of multicast. If your
machine does not have a problem chip you can <a
a kernel</a> without the line: 
<pre>options LANCE_REVC_BUG</pre>
