Cannot compile ndiswrapper on 6.2, missing Makefile_32.cpu

[pegasus]

Hello,

From my previous post: http://www.knoppix.net/forum/viewtopic.php?t=30273]

I have installed ndiswrapper and compile. Get the error:

make[1]: Entering directory `/UNIONFS/usr/src/linux-headers-2.6.31.6'
/UNIONFS/usr/src/linux-headers-2.6.31.6/arch/x86/Makefile:39: /UNIONFS/usr/src/linux-headers-2.6.31.6/arch/x86/Makefile_32.cpu: No such file or directory
make[1]: *** No rule to make target `/UNIONFS/usr/src/linux-headers-2.6.31.6/arch/x86/Makefile_32.cpu'. Stop.

Please advise how I can correct this problem or best please advise how I can get the precompiled ndiswrapper module for this knoppix version (kernel 2.6.31.6).
Thanks
