This is the Linksys WPC54GS on Fedora Core 3
(kernel is 2.6.10-1.741_FC3.stk16)
I used the lsbcmnds.inf.
I was getting a fatal error when I tried to modprobe ndiswrapper.
I looked in /etc/modprobe.conf and there were several lines like
alias eth1 ndiswrapper
I figured these were from previous installs of ndiswrapper, so I deleted all of these and then did ndiswrapper -m which created the line
alias eth1 ndiswrapper in /etc/modprobe.conf
And it worked.
Thought this might help someone else down the line...
