Actually as an udev package maintainer for my distro I have been 
reported several cases when /proc/sys/dev/cdrom/info gives totally wrong 
information about drives capabilities. E.g. a pure CD-ROM drive is 
reported as being capable to write RAM and MRW discs but not CD-Rs (the 
reporter also has a CD-RW on the same computer).

So probably MMC-commands can help. But I personally think that stuff 
like udev and hal should rely on kernel correctness rather than 
re-inventing checking code again and again, and bugs like that must be 
solved on kernel level.
