Thanks for the quick reply.  That's what I figured...I was confised a bit, 
because the FAQ doesn't mention a higher value than 1024 (which seems to be 
the default value on 1.5 anyway, or at least for -current).  I just 
reconfigured my kernel with option NMBCLUSTERS 8192 and config didn't 
complain.  Compiling now...

netstat -m works too :-)
