I am new to the Linux community and I have a few questions which I hope have simple answers.

Can RTLinux be installed on Ubuntu if a compatable kernel is being used on the Ubuntu installation?

The real time application which is going to be run on this system uses a Control Area Network (CAN). There are drivers available for the CAN card for Linux kernels which are compatable with my version of RTLinux. Can the real time application use this hardware running in the RTLinux kernel or do I need additional drivers for the RTLinux kernel.

Thanks for taking the time to look over my questions.
