The result  of this command (at the end of your mail) clearly indicates
that this is a multi-session disk, do you can't expect to be able to copy
its contents with dd;
Why kernel 2.2.19 is able to read this disk, while 2.4.6 cannot is another
problem. Either 2.4.6 cannot handle multi-session disks (I would be
surprised if that would be case, although I have not checked), or maybe
the Windows CD-mastering/recording software you are using makes some
departure from standards, which is tolerated by 2.2.19, but not by 2.4.6;
You might want to look at your /var/log/messages file and possibly check
whether it is possible to get more debugging output from the kernel (cdrom
driver?)
