I'm not sure what you mean with "kernel", because cc65 generates programs. But
assuming you mean "program" instead of "kernel", then yes, loadable drivers
can be linked statically to the program. This is the way, platforms without
file I/O are currently using these drivers.

See the documentation for the co65 utility for more information. There's a
complete example on how to convert and link a graphics drivers.

You don't necessarily need open, read and close. Any other method to access
data will also do. Drivers can be loaded from ROM if needed and removed if RAM
gets scarce.
