I can confirm this (I'm not too happy having pointless setuid applications
around either - instead I just have rw access to the cdrom device). Here's the
sample output;

This clearly isn't an impossible problem - my Ubuntu-using friends can burn CDs
with cdrecord as a non-root user as well. Having looked over similar reports, I
should also add the information that I'm using Linux, not Solaris. That is, I'm
using Linux, not Solaris, Solaris isn't relevant. Linux is.
The CDROM device is IDE, and strace confirms for sure that cdrecord was opening
the correct device.
