Bing ! The sound of a light bulb coming on.
The Mosfets seems to function ok at 5v, but I hate the idea of underdriving the gate. I've found IRL540 from Futurlec here in Oz whcih have the logic drive input - and for only $0.70 each.

For years now I have been running IRF530's with only 5V on the gate 1-3A drain to source current for cheap switchmode devices, I just wanted to second that this does work, not as well as logic level but, for cheap low current switch mode stuff I have had no problem (I always included snubber/flashback diode (D-S) of coarse but for the poor man, linear range is good enough.
