I'll do that and see, the script works on -current. My main reason for 
staying on 1.6.1 is that this machine is supposed to be the "stable" 
one. It will run the dns, ntp, etc for the other boxes, and I don't want 
to mess with it much after I get it configured properly.

The *other* box is the one that gets messed with.  :)

Is there a way to cut down the kdump output? Last night I had *lots* of 
"\0\0\0" lines. I'll read up on kdump and report back when I have something.

ciao!
