SCSI emulation is nonexistent and unnecessary in 2.6. You can write CDs 
with cdrecord without trouble. You can also save a few command line 
options by tweaking /etc/default/cdrecord. My /etc/default/cdrecord 
follows; with it I need not specify anything about my writer.

#ident @(#)cdrecord.dfl 1.4 02/07/07 Copyr 1998 J. Schilling
#
# This file is /etc/default/cdrecord
# It contains defaults that are used if no command line option
# or environment is present.
#
# The default device, if not specified elswhere
#
CDR_DEVICE=dvdrw

#
# The default FIFO size if, not specified elswhere
#
CDR_FIFOSIZE=4m

dvdrom=         ATA:1,1,0 -1 -1 ""
dvdrw=          ATA:1,0,0 -1 -1 burnfree
