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...
