EP93xx FREE-RTOS and VIC interrupts

Anybody know of a freeRTOS implementation for the Cirrus EP93xx chip?

I am trying to keep the basic set of interrupt functions used in the
original ARM port used for other devices. 

This requires a direct vectored jump to a program memory location held in
the VIC address register when an IRQ arives. In many ARMs this is simply
done by including a "ldr pc,[PC,#-0xFF0]" in the IRQ entry of the vector
interrupt table (at RAM zero). But for some reason the EP93xx doesn't seem
to implement this, at least it doesn't work here :-( 


Is there a way around it? (without modifying the RTOS code) i.e. how can I
implement a jump to the contents of the VIC1 vector register (at
0x800B0030) without using any other CPU registers, or saving anything on
the stack?
