>Description:
	After the last changes to the IDE code (those to speed up detection
	of drives when there is no slave present), drives set up as slave
	are not recognized any more.

	This is with a recent kernel:

ghost detected
wd0 at pciide0 channel 0 drive 0: <WDC WD800JB-00ETA0>
wd0: drive supports 16-sector PIO transfers, LBA48 addressing
wd0: 76319 MB, 155061 cyl, 16 head, 63 sec, 512 bytes/sect x 156301488 sectors
wd0: 32-bit data port
wd0: drive supports PIO mode 4, DMA mode 2, Ultra-DMA mode 5 (Ultra/100)
wd0(pciide0:0:0): using PIO mode 4, Ultra-DMA mode 5 (Ultra/100) (using DMA data transfers)
ghost detected
atapibus0 at pciide0 channel 1: 2 targets
cd0 at atapibus0 drive 0: <TOSHIBA DVD-ROM SD-M1612, , 1004> cdrom removable
cd0: 32-bit data port
cd0: drive supports PIO mode 4, DMA mode 2, Ultra-DMA mode 2 (Ultra/33)
cd0(pciide0:1:0): using PIO mode 4, Ultra-DMA mode 2 (Ultra/33) (using DMA data transfers)

	And this with the old one:

wd0 at pciide0 channel 0 drive 0: <WDC WD800JB-00ETA0>
wd0: drive supports 16-sector PIO transfers, LBA48 addressing
wd0: 76319 MB, 155061 cyl, 16 head, 63 sec, 512 bytes/sect x 156301488 sectors
wd0: 32-bit data port
wd0: drive supports PIO mode 4, DMA mode 2, Ultra-DMA mode 5 (Ultra/100)
wd1 at pciide0 channel 0 drive 1: <FUJITSU MPG3204AT E>
wd1: drive supports 16-sector PIO transfers, LBA addressing
wd1: 19546 MB, 39714 cyl, 16 head, 63 sec, 512 bytes/sect x 40031712 sectors
wd1: 32-bit data port
wd1: drive supports PIO mode 4, DMA mode 2, Ultra-DMA mode 5 (Ultra/100)
pciide0: primary channel interrupting at irq 14

pciide0: secondary channel configured to compatibility mode
atapibus0 at pciide0 channel 1: 2 targets
cd0 at atapibus0 drive 0: <TOSHIBA DVD-ROM SD-M1612, , 1004> cdrom removable
cd0: 32-bit data port
cd0: drive supports PIO mode 4, DMA mode 2, Ultra-DMA mode 2 (Ultra/33)
cd1 at atapibus0 drive 1: <PLEXTOR CD-R   PX-W1210A, , 1.10> cdrom removable
cd1: 32-bit data port
cd1: drive supports PIO mode 4, DMA mode 2
pciide0: secondary channel interrupting at irq 15
cd0(pciide0:1:0): using PIO mode 4, Ultra-DMA mode 2 (Ultra/33) (using DMA data transfers)
