Garmin's data sheet says the GPS 18-LVC takes 60 mA.
TI's data sheet for the MAX207 says typical short circuit current
is 10 mA.
It wants between 4 and 5.5 V. Even if you find a driver with enough
current, there is no guarantee that the voltage will be reasonable.
Probably better to use the USB trick. I've seen similar hacks
stealing power from the keyboard/mouse connectors.
On the other hand, I have a SIIG CyberPro/CyberSerial PCI 4S that
has jumpers setup to feed out 5V or 12V on some pin. The documentation
doesn't say which pin or how much current.
