I succesfully patched, compiled and installed the mac80211 module using a hard disk installed ubuntu 9.10. On doing that I followed some online resources that I don't totally comprehend (linux nebie); nevertheless it works fine.

Now I want copy & install the patched modules on other Ubuntu installations (without doing this whole stuff of getting kernel source and compiling). I just want to install the mac80211 module from the one Ubuntu onto other Ubuntu installations.

e.g.
*) ubuntu 9.10 on a pendrive
*) ubuntu 9.10 in a virtual machine

1)
How can I do this ? With what topics should I be familiar ? Can you give me any resources/links/keywords, what I should read, comprehend ? What should I read?

2)
Is there a tutorial how to port compiled components from one installation to an other ?

3)
does it make sense to do future compiling in a virtual machine and move the compiled modules into a hard disk or pendrive based Ubuntu (of the same version) ?

THX in advance
