DVD+RW gone missing on moving to kernel 2.6.6

[Graham Williams <Graham.Williams@togaware.com>]

My "_NEC DVD+RW ND-2100AD, ATAPI CD/DVD-ROM drive" that is easily
identified under 2.4.25 (as /dev/hdc) goes missing under my 2.6.6
kernel. dmesg has no hint at all of the DVD. This is my only IDE
device (using a SATA hard drive).

Is this a matter of finding the right module? The machine is sid,
up-to-date.

Graham
