I have a Dell Mini 9 and I followed these instructions to get MeeGo see the WiFi on the dell mini 9:

You've got to re-run the process when you update the system. At least I had to.
One issue I've got now is that is see the Wifi at boot, but won't connect automatically until I turn it off and then on again (from the Network panel).
After that it works fine.
I also have the issue of the blank screen right after boot. It's like it runs the screensaver right after logging in.
I didn't have any issues at all a part from these ones.
Note: I didn't try the DVD issue on USB as I don't own one.
Also note: when re-compiling the module after an update (you may not need to do it at EVERY update, rather at every kernel update, I guess) you need to re-install the package with --force:
Code:
sudo rpm -ivh --force ~/rpmbuild/RPMS/i586/wl-kmod-5.60.48.36-1.meego.i586.rpm
