I'm running a ppc440gx with CF connected directly to the local
bus in true IDE mode.  I use the standard ide code within u-boot
and modeled the linux driver after drivers/ide/ppc/cpci405ide.c

Perhaps more geared toward your processor:

Only difference btw the app note and what we use is that we
connected PerData[0:7] to CF_DATA[7:0] and PerData[8:15] to
CF_DATA[15:8].  Using a stride of 2.

Any other questions, you may want to hit me offlist.
