My wife's last two laptops have both had 'SCSI' CD/DVD -- firewire on the Vaio and SATA on the Lifebook. Neither time have distros been prepared to deal with such things ;-( http://www.leog.net/fujp_forum/topic.asp?TOPIC_ID=9038 shows it's not just my distro of choice that has problems with SATA ATAPI. Unfortunately, the one-line change to enable that by default was too late for 2.6.16, according to jgarzik. I just hope all the distros patch it.
