That's certainly possible.  Would be something like (note, I said
"like" I haven't done it, read the manpages to make sure I'm right
before attempting):

1) build a directory tree of what you want on the CD to boot under
   some directory (we'll call it dirname)
2) make a rescue floppy with 
   mkrescue --root=/dev/cdrom
3) copy the floppy to an image on your disk somewhere with 
   dd if=/dev/floppy of=/dirname/boot.img
4) make a bootable  ISO image of the directory tree and boot floppy
   with:
   mkisofs -b boot.img -o rescue.iso /dirname 
5) write the CD image with cdrecord:
   cdrecord dev=/dev/sg0 boot.img
 
The tricky bit might be figuring out what you want on the CD, and
possibly figuring out what to do with /var (should be writable) and
where to mount the hard disk partitions.

That all being said, there's probably rescue CD images for your distro
out there somewhere, which would let you skip to step 5 :)
