ndiswrapper FC5 works w/kernel 2.6.15-1.2054 but not 2.6.18-1.2200

I've been trying for days to get ndiswrapper to work with my FC5 installs on three different machines with no luck. I finally decided to reinstall FC5 on all three machines(for about the 3rd time each). This time I did not upgrade my kernel to the newest kernel, 2.6.18-1.2200, before installing ndiswrapper. Running the old kernel 2.6.15-1.2054 on all three machines works fine with the ndiswrapper install. If I update the kernel on any of the machines ndiswrapper will not install properly again. Yet I can go back to running the previous kernel and it will install fine.

I've followed all the instructions for the install I can find. I've installed kernel-devel first after a fresh install of FC5 and a kernel update but still no luck. I can only get my wireless up and running using the old kernel. I've been using ndiswrapper 1.27 and 1.28. Are these versions not meant for the 2.6.18 kernel?

I'm new to Linux and just happy to be finally up and running wireless, even if it is on the older kernel. I'm just wondering why all three of my machines will work using kernel 2.6.15 but not with 2.6.18? Is there something I could be doing wrong? I do the kernel update before doing the
yum install kernel-devel
, so I should be getting the right kernel-devel package for the 2.6.18 kernel, right?

If in fact 2.6.18 is not going to work. Is it possible to uninstall the kernel update? Is that just as simple as editing the grub to not display the boot option or can I actually remove the entire thing with a command like
yum uninstall kernel 2.6.18-1.2200.fc5-i686

I should clarify that the install into the 2.6.18 kernel goes smoothly enough. I just can't get wlan0 to activate. It seems no matter what I try I get a device not present error. The driver is loaded and the device is listed as present when I run
ndiswrapper -l
. When I run dmesg after modprobe ndiswrapper on the 2.6.18 kernel I find that ndiswrapper did not load properly and no wireless device had been found or loaded. When I do the same steps using the 2.6.15 kernel it loads fine.
