We have used this combination a while ago, before switching
to the ppc.
We have implemented a little boot loader which loads the image from
a separate partition of the compact flash card. The kernel partition
is written raw using dd either from a PC + card reader or from a running
uClinux with system ace driver. The boot loader just copies the raw 
data from this partition to the memory and afterwards jumps to the
start address. By this approach we can change the kernel easily
without having to generate the ace file. Furthermore we have several
images on the CF Card to choose from. So in the case that a new
kernel does not run properly, we can start another kernel.
Another advantage of using a CF Card is, that you can put your
programs onto the CF Card as well, so that you do not have to 
exchange the whole image.bin when developing user applications.

Cheers,
Erik
