Okay, so that's a resounding - "what are you smoking Ryan?" :)  When i
briefly tried it I got some complaint about device not accessible or
some such - i just got started on the dd and assumed that kind of thing
was not possible.  Will try again with brain attached.

DMA was not specifically enabled, I overlooked that.  I didn't know what
to do with blocksize to achieve any benefits, so I left that as
default.  I'll have another bash tomorrow - the machine is at work, it
might be finished by tomorrow morning ;)

Thanks guys,

Ryan
