OK, I'll start adapting the iopl() and ioperm() functions
to set the CAP_RAW_IO in cap_used, so we can know when a
process has actually used this function.

Then we just hope for the other architectures to set this
bit too. (what do we do about 68k? they just mmap() the
frame buffer, so maybe it's safe to kill the X server on
that architecture?)
