I access /dev/cdrom and it points to a major/minor combination listed in
some table. The kernel realises that it doesn't have a driver for that
major/minor combination and loads it from a lookup table (symbols.map
or something).

Hmmm. I mount my swimdress when I want to go swimming, not when I see
the water. Can't a kernel do it similarly?
