I have to say though I've had processes dump core the first time I've tried doing I/O port accesses after calling i386_set_ioperm() on 5.x since 5.0. This behaviour is sporadic. With opening /dev/io, I have had no problem. Also, the /dev/io method appears to work on amd64, whereas the i386_set_ioperm() method does not. BMS
