[lug] IDE cd writer config

[Tony Dyson]

I've been reading the docs & usenet postings on this topic, & I also
discovered this section in RH 7.2 /etc/rc.sysinit:

# If they asked for ide-scsi, load it
if grep -q "ide-scsi" /proc/cmdline ; then
        modprobe ide-cd >/dev/null 2>&1
        modprobe ide-scsi >/dev/null 2>&1
fi

I've not yet found what instruction you'd have to add to /proc/cmdline
to trigger this section. Has anyone used it, & should it be sufficient
to enable the device? It seems "sparse" compared to the suggestions in
the how-tos.
