I suggest that you write a small C library that implements the operations that 
you need, and then wrap that with PInvoke.  Or use PInvoke to import the libc 
open/read/ioctl routines and call them directly like you would in C code.  I 
personally would use the former, because it will be easier to port to new 
platforms with different joystick drivers.

It isn't really feasible to provide generic access to Posix via C#.  The ioctl 
system call, in particular, varies a lot between systems and OS versions, and 
wrapping it in a way that would make it useful is just not possible.  But if 
you wrap the ugly bits with C first, you can avoid the problem.

Cheers,

Rhys.
