Have you looked at any of the stuff in sys/i386/isa lately?  Some
of it is *so horrible* that it is almost unbearable.

Take a look at gpib.c for example:
        /* Have memory for buffer? */
        sc->sc_inbuf = malloc(BUFSIZE, M_DEVBUF, M_WAITOK);
        if (sc->sc_inbuf == 0)
                return(ENOMEM);

        if (initgpib()) return(EBUSY);
        sc->sc_flags |= OPEN;
        sc->sc_count = 0;
        oldcount=0;
if (unit!=0) {  /*Someone is trying to access an actual device*/
                /*So.. we'll address it to listen*/
enableremote(unit);
 do {
 status=inb(ISR2);
 }
 while (!(status&8)&&tsleep((caddr_t)&gpib_sc, GPIBPRI,"gpibpoll",1)==EWOULDBLOCK);

 outb(CDOR,(unit&31)+32);/*address device to listen*/

 do
 status=inb(ISR2);
 while (!(status&8)&&tsleep((caddr_t)&gpib_sc, GPIBPRI,"gpibpoll",1)==EWOULDBLOCK);
 outb (CDOR,64); /*Address controller (me) to talk*/
 do status=inb(ISR2);

 while (!(status&8)&&tsleep((caddr_t)&gpib_sc, GPIBPRI,"gpibpoll",1)==EWOULDBLOCK);
 outb(AUXMR,gts); /*Set to Standby (Controller)*/


 do
 status=inb(ISR1);
 while (!(status&2)&&tsleep((caddr_t)&gpib_sc, GPIBPRI,"gpibpoll",1)==EWOULDBLOCK);
/*Set up the TURBO488 registers*/
 outb(IMR2,0x30); /*we have to enable DMA (0x30) for turbo488 to work*/
 outb(CNT0,0);   /*NOTE this does not enable DMA to the host computer!!*/
 outb(CNT1,0);
 outb(CNT2,0);
 outb(CNT3,0);
 outb(CMDR,0x20);
 outb(CFG,0x47); /* 16 bit, write, fifo B first, TMOE TIM */
 outb(CMDR,0x10); /*RESET fifos*/
 outb(CMDR,0x04); /*Tell TURBO488 to GO*/
}
        return(0);

There is much much more, but this stuff is *truely* horrible.

Cheers,
