IDE driver in polling mode

[Michael]

Hi.
I have a board with MPC8541(PPC PQ3) platform running 2.6.14 Linux.

I'd like to know whether it is possible to use IDE driver (ide-disk)
in polling mode, instead of using IRQ.

In case you wonder - the reason why I need this weired thing is that I
have a compact flash connected directly to the host local bus using
memory mode. It is more-or-less IDE-compatible, except that it doesn't
issue interrupts.

Thanks,
             Michael.
