I would advise to not do this: since disabling current limiting etc
will cause a large problem in the case of a short circuit thereby no
protection to the hardware. In such an event, it could probably damage
the tracks carrying power on the card as well as the tracks on the
motherboard, and in some cases the gold finches themselves and or the
PCI connector.

Generally, there are only a few devices capable of sourcing > 0.5A, So
I wonder ....
