Using ndiswrapper on the LiveCD version

Hi there guys.

I have started to use your LiveCD version of SimplyMEPIS 3.3.1 (test 1). The OnTheGo feature is great for saving my docs and my settings. However, a number of the PCs that I use all have wireless ethernet cards. So I tried to setup the drivers for one of the MANY DIFFERENT cards using the ndiswrapper by doing the following.

ndiswrapper -i NET8180.INF
ndiswrapper -d 1799:6001 net8180
ndiswrapper -l

The list switch shows the net8180 driver and says present beside it, so thats all fine.

I then do:

depmod -a

but that comes up with an error about write access to a file, which also comes up when I do:

modprobe ndiswrapper

Its obviously becasue that module files are all on the CD. Is there any way round this? Re-directing the files to the pen drive? Re-building the CD from windows to have the drivers built-in and ready to go?

Im fairly new to linux in general, so go easy on me.
