Thos lines are either a typoe or ansolutly incorrect. wdcx is the name of 
the controller, while the device is wcd0, like so:

controller      wdc1    at isa? port "IO_WD2" bio irq 15 vector wdintr
device wcd0

The other thing - the CD is alwats wcd0, no matter what controller it is 
on. However, at least for me (and from the traffic on this list - for 
many other as well), ATAPI CD-ROMs work *only* as the slaves on the 
primary controller. Try moving it there.

The probe on my machine (disks as masters on both controllers, and CD as 
the slave on the primary controller) looks like so:

wdc0 at 0x1f0-0x1f7 irq 14 flags 0x800080ff on isa
wdc0: unit 0 (wd0): <WDC AC31600H>, 32-bit, multi-block-16
wd0: 1549MB (3173184 sectors), 3148 cyls, 16 heads, 63 S/T, 512 B/S
wdc0: unit 1 (atapi): <CREATIVE CD821E/1.05>, removable, dma, iordis
wcd0: 0Kb/sec, 240Kb cache, audio play, 255 volume levels, ejectable tray
wcd0: no disc inside, unlocked
wdc1 at 0x170-0x177 irq 15 flags 0x80ff on isa
wdc1: unit 0 (wd2): <WDC AC2850F>, 32-bit, multi-block-16
wd2: 814MB (1667232 sectors), 1654 cyls, 16 heads, 63 S/T, 512 B/S
