>Description:
	on a DS10 (options DEC_6600) configured with devices as:

COMPAQ AlphaServer DS10 466 MHz Console V5.5-5, Sep  1 1999 09:05:08
>How-To-Repeat:
	see above.

>Fix:
	not exactly sure.
	in sys/arch/alpha/alpha/dec_6600.c::dec_6600_device_register()
	it seems to match the cd first. we think it's ignoring the ide
	channel.

	here's the dmesg with
		#define DR_VERBOSE(f) f
	and the #if 0's in autoconf.c changed to #if 1:
