I havent really been scrutinizing the hardware details of this upgrade
discussion but I have a question:

Is it possible to build this board so that it contains PROVISIONS for
both upgrades and allows the installer to select just the one they
need via a jumper setting or presence of an IC? This way the board
could be built with the idea of a combined upgrade in mind and if
you dont need the P5.1 upgrade you dont enable it. Two versions
could be distributed, one for a combined upgrade and a cheaper one
without the necessary parts for the P5.1.
It may add to the cost/complexity a bit but it seems to me if you are
adding 2 MAXTORs to your box, $5 more you aren't going to miss.
Is it possible?

Me, I want both in one shot.
