Hi Justin,

> If I add the jumper does then I will need to use a regulated 5V supply right?

No, but it would help.

> Can I go lower like to 4.5V? This just bypasses the regulator right?

It bypasses the regulator on the robostix board (that feeds voltage to
the gumstix). The gumstix still has its own regulator.

Going lower might work, but the voltage regulators on the robostix
really want about 5.15v. I'm not sure of the consequences (if any) of
using a lower supply voltage.

Nope - it's because the wifi module consumes alot of power. Mine gets
hot enough that it hurts to touch it.

> Why would the module get hot and not the netmicroSD board?

Because its the circuitry on the wifi module that's generating the
heat. If you run a netwifimicrosd board with no wifi module, the board
only gets slightly warm.
