4- Do you have any unused pins left on the 7128S? The CF/IDE interface doesn't have its IRQ signal attached to anything. I've never written a polling driver in Linux before. I don't know what issues will come up as a result.

Mike,
Returning to your original question about whether there are spare pins on CPLD for CF interrupt: yes, there are two spare pins; it is not difficult to wire CF interrupt to one of the spare pins; add a pull resistor; and modify the CPLD to add a level 2 autovector.
Bill
