Porting CANFestival to RTEMS

I guess it's time to learn more about the RTEMS runtime linker.
I do have a few specific questions:
What pat of CANFestival are you using?
What timer driver/library are you using?
What CAN driver are you using?
How did you glue the pieces together? Did you compile it by modifying
the posix/unix drivers, or go the more bare metal based off the AVR? Is
RSB involved? I'm stuck figuring out what I need to do, and what is the
minimum required support infrastructure to get CANFestival to work. It
seems like you need read, write
Would you be willing to provide some code?
Would it make sense for us to team up with the CANFestival developers to
make a robust RTEMS port?
