/dev/cdrom is a link to the proper device, if that link is not on the initrd /dev/cdrom won't work.
I previously had some statically linked linuxrc C code (I don't have the code anymore- it was a work-for-hire), that scanned the various locations that the cd could be (/dev/hd[abcd...]) and looked for specific files that it expected to be on the cd, once it found it it setup real-root-dev to be proper for that device.
This work rather nicely in situations where the location of the cd drive was not the same from one machine to another, and was rather simple to write.
