Hm, when I first tried to use the 64bit Windows driver for my FRITZ!WLAN
USB Stick N 2.4 I saw
ndiswrapper (import:242): unknown symbol: ntoskrnl.exe:'NlsMbCodePageTag'
I checked the SVN of ndiswrapper and found a change that should make
this symbol resolvable. And indeed, the SVN trunk version of ndiswrapper
worked for me.
But I don't see anything similar for the unknown symbols you get
reported. So I doubt that building ndiswrapper from SVN will help you.

I don't think that you can use the 32bit driver on a 64bit system.

Don't know. If there's a 64bit XP driver available, I'd try this one.

Nevertheless, it could be that you are simply out of luck wrt the
combination Windows driver/ndiswrapper.

But maybe one of the tips found here

will work for you and you get a stable WLAN connection without using a
Windows driver.
