Allright. As far as I can tell it is 5V card.
The red PCI book
Chapter 15 : MECHANICAL SPECIFICATION
CONNECTOR PHYSICAL DESCRIPTION PG 471
[..] The same physical connector is used for the 32-bit signaling
environment voltages. In one orientation the keys accept 5 volt
boards. Rotated 180 degress, the connector accepts 3.3 volt
signaling boards. The pin numbering of the connector changes (!)
for the different signaling environemtns to maintain the same
relative position of signals on the connector.
For what it is worth, if anyone needs MiniPCI Port-80 boards:
