The thing will boot with 2 SM-51, inspite of what the docs say, Theo has
told me that it is fixed. He has also told me that it will now boot with the
SM-100, although I have not yet been able to make that happen. My
undertanding is that there is a flaw in the SM-100 modules that generally
prevents them from booting OBSD.

That would be cool, although the box with boot with 2 modules, alas, no SMP.

Not sure if I want to sell the 4/600's just yet. I still have 5 working
4/630 MP and 6/670 MP boxen.
