Time to panic
sudo nvram boot-args="maxmem=1024"
To set it back, use:
sudo nvram boot-args=""
I also found reference to a panic.log file during my google trolling, so I dug around, and found that it did record the KPs. I grabbed the first line from the last one, put it into google, and came back with the diagnosis that there was a good chance it might be the airport card.
It turns out that a) I just recently started using the airport connection on the mini because I had to move my setup down to a spare bedroom while I work on my home office in the attic where my hard-wired ports are. b) The only reason I was running Parallels was so my son could stream Noggin videos online, which only runs on windows. So the kernel panics were always happening during high network usage.
I guess this is motivation to get the darn attic finished.
