RC as in Resistor-Capacitor I would guess. Use an inline resistor from the 5V line to charge a capacitor. The voltage on the capacitor rises more slowly than the voltage before the resistor. This still gives you a slowish edge - a schmitt trigger would sharpen this up if this still causes grief.

The delay can be altered by the values of R and C. Bigger R means smaller charge current and a longer delay. Bigger C means more charge needed to raise the voltage on the capacitor, and a longer delay.

So far, I'm thinking about modifying Sproggy PSU, daisy chaining the MAX ICs to gain more power handling (if that's possible). That would take care of the power issue, but as for the power good signal, i don't know
