feisty ndiswrapper 1.38 windows driver not 32-bit error

[golfer]

I'm running feisty and was unable to get my dell 1500n wireless
working under ndiswrapper 1.30.  But, the wifi works under edgy with
ndiswrapper 1.3.1.  On feisty, the latest update to ndiswrapper 1.38
should have fixed it, but now I get a strange error about 32-bit.

I'm using the same dell driver that I have use before, and the one
recommended on the wiki.

golfbuf :~$ ndiswrapper -l

When I modprobe, it does not activate it.  The dmesg errors are:

golfbuf :~$ sudo modprobe ndiswrapper

golfbuf :~$ sudo iwconfig
lo        no wireless extensions.

eth0      no wireless extensions.

golfbuf :~$ dmesg

The system log has the same messages.
