But all miniPCI cards are (also) 3.3V-only, and thus all the chipsets 
are 3.3V (only), so it would be
really strange of some hardware vendor to build anything but a 3.3V 
802.11 card.

Note that the PCI card on the 48xx has up to 10W of combined 3.3V and 5V 
power available, and
according to the manual, an onboard DC-DC converter supplies +12V @ 0.3A 
and ­12V @ 0.1A to the PCI connector.

The 45xx is a little different, as there is only 3W available on the 
3.3V power pins, there is no power available on the +12V and ­12V power 
pins. and when using the DC Input Jack as the power source, only very 
limited amount of power is available on the 5V pins, as the 5V is then 
supplied by a linear regulator.  The 45xx is keyed for 3.3V cards only.
