Having just been there recently:

Firstly, my crt0.S does a copy from romvec to ramvec and then sets the
IVR to point to ramvec.
The crt0.S for 2.4.x also contains an initial romvec.

My arch/m68knommu/platform/68360/ints.c contains another table that is
written later, and
then each driver will enter its own vectors as required (eg. traps.c,

Hope that helps sufficiently with your setup.
