Have a look at the top of the loop in __wdcwait_reset():

        /* wait for BSY to deassert */
        for (timeout = 0; timeout < WDCNDELAY_RST;timeout++) {
                if (chp->wdc->cap & WDC_CAPABILITY_SELECT)
                        chp->wdc->select(chp,0);

Then, after a few bus_space_read's:

                if (chp->wdc->cap & WDC_CAPABILITY_SELECT)
                        chp->wdc->select(chp,1);
