I think the problem was that this variant didn't use the standard RTEMS 
exception support, but this is three years ago, so I may be wrong.

So, gba installs the dispatcher with the help of _ARMV4_Exception_interrupt which in turn branches to bsp_interrupt_dispatch while handling an interrupt. Since bsp_interrupt_dispatch being a C function. how is the assembler able to reference it's address ?

The assembler is not responsible to resolve the references.  This is the 
job of the linker.  If you get an undefined reference, then the linker 
doesn't see the definition.

You probably have a problem with the linker command line here.
