Create bootable CD with custom kernel

[Pip Oomen <pip@gan.no>]

I am currently trying to get Debian running on an Apple Xserve G4/133DP, 
but, as discussed with Sven Luther, it turns out the current pmac kernel 
does not include the correct IDE driver. While the change in the kernel 
makes its way into the nightlies, I was wondering if it is possible to 
build my own CD image.

One thing that is complicating this however, is the fact that the 
building process is not capable of cross-building, and I am currently 
lacking any PPC machine to do the build on, although I did succeed in 
cross-compiling the kernel.

Now, is anyone aware of a way to take today's nightly and somehow 
replace the kernel image with one I built myself?

Kind regards,

Pepijn.
