Here's what I'm doing:
gumstix <--- serial com uart ---> gp3 <--- pwm --- Dual-axis Accelerometer
gp3: ($49)

8 general purpose I/O lines (digital input/output with special features like PWM or pulse output)


5 10-bit A/D inputs (separate from digital pins)


1 hardware PWM output (operates continuously)


1 hardware counter input (operates continuously)


1 LED under software control

Memsic 2125 Dual-axis Accelerometer: ($29)
Now there is a Tri-axis Accelerometer you can get through parallax.  Here is a link to different sensors:
I actually bought the robostix, but haven't gotten around to using it, so I can't give you much advice on it.
