I guarantee you are not tripping. :(

I can try to help, but I am also busy (crunch-time at work).
My system is an Asus P5K-E/WiFi with a DVDR <LITE-ON DVDRW
LH-20A1S/9L08>. It has 4GB RAM and two SATA hard drives. I have no
PATA drives in it. It is running in RAID mode.
Unfortunately, this is my only workstation at home, so I will not be
changing versions. I am willing to make changes to the driver. Here is
a patch to recognize and print the ICH9R during boot. It does not
change anything functionally.
My current notes:
1. burncd (without atapicam loaded), cdrecord and dd can all produce
dd if=/dev/acd0 of=/dev/null bs=10M count=1
2. sysinstall will fail during install when copying GENERIC kernel.
This was on my work computer in a Dell Optiplex 745 with 1GB RAM.
atapci0: <Intel ICH8 SATA300 controller>
acd0: CDRW <HL-DT-ST CD-RW/DVD-ROM GCC-H10N/C103> at ata3-master SATA150
3. Do not detach a channel with atacontrol. I tried that on the channel
with the DVD drive. Panic.
4. I am thinking about writing a program to perform simple tests on the
ATAPI ioctl's. Maybe one exists?
5. PATA is not related since I have no PATA drives in my computer.
