Yeah, I suspect so.

On x86, <sys/io.h> provides the following functions:

  ioperm
  iopl
  inb
  inp_p
  inw
  inw_p
  inl
  inl_p
  outb
  outb_p
  outw
  outw_p
  outl
  outl_p
  insb
  insw
  insl
  outsb
  outsw
  outsl

So you can look for those and see what the program is doing.  If it's
really doing direct I/O to hardware ports, then you'll have quite a bit
of work ahead of you to figure out how to port it to a different
architecture.  But maybe you'll be lucky and it's just a spurious
#include.
