If it helps: I get the same errors with kernel 2.6.9 (still). It might
have something to do with some change in the handling of setuid
applications, which also force me to run cdrecord as root, not as
suid-binary and as normal user. 

Strange thing: Other software does run setuid, e.g. cdrdao or
growisofs.

Ciao
