The way the backwards-compatibility is _meant_ to work is that a driver
can just do this:

#ifndef IRQ_RETVAL
typedef void irqreturn_t;
#define IRQ_NONE
#define IRQ_HANDLED
#define IRQ_RETVAL(x)
#endif

and after that you can just use the 2.5.x semantics even with a 2.4.x
kernel.

Which is nice and clean, and allows you to support old kernels _without_
having any translation layer.
