yes, this is possible.
I've had to do it myself - it takes a bit of fiddling/hacking though.
bearing in mind that:
1. cobbler doesn't support multiple initrds directly
2. cobbler deletes everything in your tftproot on a 'sync'
I managed this by putting the driver disk images in a different directory
under /tftpboot (or wherever your root is) and editing the pxeboot templates
in /etc/cobbler to manipulate the append lines for particular
distros/profiles etc.
These files are just templates like kickstarts and snippets so you can use
cheetah instructions to manipulate the initrd= parts.
There is an option now that copies files to your TFTP directory for you:
--boot-files=BOOT_FILES
And then either use kopts/ksmeta or manually edit the templates as
Stuart did. The difficulty will be in the fact that you're modifying
the initrd option, which is generated in the $append_line variable.
You'll probably have to write some cheetah code and do some string
manipulation in order to do what you want above.
