ndiswrapper problems

[James Thorpe]

Hi,

I'm trying to get my wireless up and running, I've downloaded and 
built/installed ndiswrapper, and have used it to install my wireless 
driver.  The next step in the instructions 
(http://ndiswrapper.sourceforge.net/phpwiki/index.php/Installation) says 
to do:
    modprobe ndiswrapper

but the output of that is:
    FATAL: Error inserting ndiswrapper 
(/lib/modules/2.6.10-1.770_FC3/misc/ndiswrapper.ko): Unknown symbol in 
module, or unknown parameter (see dmesg)

dmesg says:
    ndiswrapper: Unknown symbol get_user_size

I'm using a fresh install of FC3, yummed to the latest versions 
yesterday (2.6.10-1.770_FC3)

Any ideas where to go next?

Thanks,

James.
