Surely the address gets stored in the exception frame somewhere?

Well. There is already some logic there for EXCP_ADDRESS in m68k_interrupt_all() so I
thought this would just work as-is, but upon closer reading of older CPU datasheets
it appears there are at least 2 different stack frame formats for CPUs before the 68040.
It looks like I'll have to do a bit more research before posting a v2.
ATB,
Mark.
