I have 2 of these cards still, and have been mucking about just  
trying to get *any* kind of install to happen using them with FreeBSD  
(their specs are *soooo* much nicer than my Adaptec cards, at the  
same price...)

With that, I'm willing to start hacking through this problem- I'll be  
working with the cards either tomorrow, or Saturday- (depending on  
the Strike, and a few other variables)...

Gordon- Do you have one of these cards too?  I'm wanting to start  
pooling notes on this or something...
I'll try to jump on irc.freenode.net #nycbug when I'm working- my  
nick is dot_ike.

Rocket-
