A collegue of mine has an Intel mainboard with the i865 chipset onboard
(DQ965). All kernels up to and including 2.6.22-rc2 do not detect the IDE
CDROM/DVDROM when booting. The SATA hard drive is found without any
problems.
Relevant parts from lspci:

What's interesting here is that 00:1f.2 and 00:1f.5 are both identified as
"n port SATA" controllers even though one of them (I suspect 00:1f.5) is a
PATA controller. This may just be a typo in lspci's database though.

Here the HDD is clearly detected while the CDROM/DVDROM (attached to ide0)
isn't.
libata is compiled into the kernel as is the non-libata PATA driver.
In the libata configuration, only SATA_AHCI, ATA_PIIX and ATA_GENERIC are
defined. For the non-libata side of things most options are selected
including BLK_DEV_IDE, BLK_DEV_IDECD, IDE_GENERIC, BLK_DEV_IDEPCI,
BLK_DEV_GENERIC, BLK_DEV_IDEDMA_PCI and BLK_DEV_PIIX.
Does anyone have any ideas as to why there is a problem detecting the PATA
(IDE) CDROM/DVDROM in this machine? Further information/testing can be
provided if requested.
A lot of newer Intel boards have the IDE interface provided by an
external JMicron, etc. chip so you may need to enable that driver for
things to work.
Also, it's unrelated to this problem, but you should check the BIOS
settings for the SATA controller - you really want to get the controller
into AHCI mode for best performance.
