Compact Flash on 8349mITX

Hello All,

I'm using the latest 2.2.26 kernel image from
linux/kernel/git/benh/powerpc.git on a mpc8349mITX, and trying to get
Compact Flash to work. The kernel booted fine, but I was surprised to
see Compact Flash IRQ was not being handled. Does irq polling need to be
used for compact flash to work with this version of the kernel on this
board?

Here's snip of the unhandled IRQ, for your edification.

irq 23: nobody cared (try booting with the "irqpoll" option)
