>Description:
My i386 system running 6.0_BETA (netbsd-6 sources as of 2012.03.12)
doesn't detect IDE CDROM drive. It is attached to an
internal IDE controller.

Motherboard is GA-8I945GMF.

Additional USB controller and ethernet card are plugged in into PCI slots.

Kernel is GENERIC. 

Full dmesg output is here (for 5.99.60)

Linux detects cdrom drive without problems.
If it helps Linux's dmesg output is available here
