this is the way I _don't_ want to go ... I just want something cheap
and cheerful on this occasion. I'm warming to the idea of running some
cables to the gap above the cupboards and fitting fluorescents there
eventually. So given that the current Centre lamp is a 65W 5 foot
strip, what sort of uplighting wattage should I be thinking of?

You should paint the ceiling matt white (titainuim dioxide) for
maximum reflection and diffusion. Also make sure tops of cupboards
are white (doesn't need to be matt). You will need more power
because of losses at non-perfect reflective surfaces.
What is the length of the cupboard run?
Are you thinking of any other lighting in the room, such as
under cupboard, down lighters or uplighters on the other side
of the room, etc?
What height of object is the largest you can stand on the top
of the cupboard at the back, and yet it not be visible when you
are standing at the other side of the room?
