I don't think udev does anything with this, hal is the task that polls 
to see when a disc has been inserted.

 From what I can tell it looks like this is due to some broken 
assumptions in HAL that I described in this RH Bugzilla entry:

https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=201533

Essentially it seems to assume that any sysfs filename like sr0 which 
ends in a number corresponds to a partition, which in this case (and 
likely others) is wrong. This looks to have been fixed in the HAL git 
repository but hasn't made it into a HAL release yet.

IOW, from what I can see the kernel is vindicated..
