I assume that as you are running ~x86 you have upgraded to gentoo-sources 
version 2.6.13. In that version devfs has been removed (well the config 
option has gone, the code is still there). The /dev/cdroms/cdrom0 style of 
device file name is a part of devfs, so if with earlier kernels you still had 
devfs enabled in the kernel, despite running udev, then you would have gotten 
the /dev/cdroms/cdrom0 link.

I am running x86 and running with udev but with devfs still in the kernel. 
Yesterday I disabled devfs on one of the machines so that I could see what 
would break in preparation for 2.6.13 moving to x86. I experienced exactly 
your problem of /dev/cdroms/cdrom0 disappearing. Fortunately the solution is 
simple, as you describe above.
