[ale] moving CD-ROM from master to slave

Are you passing any options to your kernel at boot time? Check
/etc/lilo.conf or /etc/grub.conf,depending on which you use, and see if
you have anything indicating "hdc".

Check your modules.conf file, and see if anything shows up there.

Check your /etc/fstab file, and make sure the CDROM is right.

My guess is one of the first two, since you are getting kernel messages
about DMA settings.
