The PWM ports on other boards have DIO 5V power on the power pins because they are from the MXP. The ones on the Spartan board aren't from the MXP, they are just a pass through of the roboRIO's 10 dedicated PWM pins so they have 6v servo power.
OP, have you opened the roboRIO to examine it for debris? That would be my primary suspect if the current draw of your devices isn't changing. It sounds like you can't reproduce a scenario where this triggers?
