It is important that the (tss_system - io_port_bitmap) < 65535 (or maybe even 
32767) but that is perfectly alright in your case.

The values look fien to me.

At each task switch the IO port bitmap of the process (io_pbm[0] and 
io_pbm[1]) are mapped at the address io_port_bitmap. This is done in function 
port_map_iopbm(). Maybe you could verify that this is done correctly on your 
machine. I'd probably best try to do the same here.
