Hmm, you could try to change the probe to something like:
...
status1 = inb(scp->ioaddr + ATA_STATUS);
if ((status0 & 0xf8) != 0xf8 && status0 != 0xa5)
mask |= 0x01;
if ((status1 & 0xf8) != 0xf8 && status1 != 0xa5)
mask |= 0x02;
if (bootverbose)
ata_printf(scp, -1, "mask=%02x status0=%02x status1=%02x\n",
mask, status0, status1);
...
It seems that the 0xa5 value means "no device" too, on lots of
controllers, and its not valid anyways, so it wouldn't hurt..."
