I guess the character device is much easier to implement. However, my
current problem is that a manged to compile something and all it does is
crash the kernel. Is there a way of debugging this without going through
reboot and fsck - maybe an intermediate kernel module, a kernel
simluator? I mean, I can'T set up a virtual machine if a want to talk to
real hardware.
