	To clarify, no, the cards don't rely on the kernel's software RAID
drivers.  They provide their own drivers, but it's still run by your
cpu, and it must reside in the kernel.  

	If you can find a card that has it's own cpu (ASIC, microcontroller,
whatever) plus some RAM that'll be a much faster solution.  It'll also
be a lot more expensive!  But see Transams responce later :-(.

	Again, to calrify, I've know of very few lines that I've actually
contributed to the kernel RAID drivers.  I've read most all of it, but
I've not written a lot of the code.
