Some PCI cards have a jumper on one of the modem control signals to provide 5 or 12 V. It was used to power things like bar code scanners before USB came along. (I'll dig out a part number if anybody wants it.) If you only need a few mA, you can get that from the normal modem control signals. I have a temperature sensor that works that way. -- These are my opinions.
