Probably also not related to your actual problem, but this code likely
lacks some "volatile"'s. (You seem to be dereferencing pointers to
HW-related addresses. Normally you will have to use volatile pointer for
this purpose).

Another wild guess at your problem: Is there something like a VBR you
need to set, or some interrupt mask/register you need to set to receive
interrupts?
