>Description:
	I installed a new Panasonic DVD Multidrive.  After enabling
	atapi udma in /boot/loader.conf as follows:

	userconfig_script_load="YES"
	hw.ata.atapi_dma="1"

	I see the following in the boot messages:

	acd1: DVD-R <MATSHITADVD-RAM SW-9571> at ata1-slave UDMA66
	(Full dmesg text below)

	The drive does not function in this mode, but produces I/O errors
	for all operations.  It works fine in PIO mode or udma33.  See
	the attached fix.

>How-To-Repeat:
	See hardware desc.
>Fix:

	Use atacontrol to force the mode of the DVD Multidrive to udma33.
	I activated this at boot time by creating the following script
	in /usr/local/etc/rc.d/dvdram.sh:

#!/bin/sh

# Place me in /usr/local/etc/rc.d to force udma## mode.
# Some DVD Multidrives default to udma66 on 5.1R, which results
# in I/O errors.  

# Examples  ( Type "man atacontrol" for modes )

# Set both channels on controller 0 to udma66
# atacontrol mode 1 udma66 udma66

# Set both channels on controller 1 to udma33
atacontrol mode 1 udma33 udma33

	I presume the same thing could be achieved in device.hints
	as well, but I couldn't find any docs on the proper syntax.
