With the latest kernel (2.1.113 or later) could you compile ide-cd in as a module, and add: options cdrom debug=1
to your /etc/conf.modules. This will cause the uniform cdrom driver to be built as a module and to dump out tons of debugging stuff to your system log when it is used. You might also try out: options cdrom debug=1 check_media_type=1
I just added these flags to Uniform to help debug this sort of stuff... Anyway, let me know if that helps to narrow down the source of the problem. I have been meaning to add this type of debugging stuff to ide-cd as well (I have a pre-patch that does this but it is not ready for public consumption.)
