See, this is why I changed the function name in the first place.
request_irq() assumes a PC-like interrupt structure, which doesn't work
on the MPC8xx internal interrupt controller.  You need to add an
indirect function call to the 'md' structure that will install the
IDE interrupt handler.  When you use the PCMCIA for ATA/IDE, you should
call a function that installs the PCMCIA interrupt vector.
