How to check for the framebuffer device and the right kernel module

I've written a simple app which checks if the framebuffer device is correct installed (see "http://wyodesktop.sourceforge.net/index.php?page=checkapp.html"). I do it by more less just using the device. My little check app is working but shouldn't there be a more correct way?

I'm also not sure what results are produced when the device exists but without the right kernel module. How can I check for a kernel module to inform the user about it?

PS. I welcome any feedback (e-mail) how this little app behaves on anyones system.
