Knoppix 3.5 DVD - Kernel 2.6 problem with DVD drives?

[probono]

Does Knoppix 3.5 DVD - Kernel 2.6 have known problems with DVD drives? Mine is recognized under 2.4 but not under 2.6 on this DVD.

My DVD drive is:

ide_info /dev/hdc
MODEL="PIONEER DVD RW DVR-106D"
FW_REV="1.07"

After further investigation, I come to the conclusion that some bug prevents /dev/cdrom from being created in the above constellation. Later versions of Knoppix don't show the bug, and in Knoppix 3.7 the same DVD drive works perfect.
