Thats pretty much the idea

the above link is realy quite helpfull you willl need to adapt some of the comands as to load your driver for your card.
but the idea is install ndiswrapper
load the windows driver
check everything works and away you go
as a note there is a different chipset used between v2 and v3 of the card so the v3 drivers that the site links to will not work for you just use the ones that came with the card or download them from the netgear site
also as your using fedora you can pass on the first 2 apt installations and use either the source or the rpm i linked to earlier
