Sylvain and I are actively working on the mpc52xx support in
arch/powerpc.  You can choose between an arch/ppc or an arch/powerpc
kernel (arch/ppc the old 32 bit support; and it is steadly being
migrated over to arch/powerpc).  If you want to stick with arch/ppc;
you can use any recent 2.6 kernel and search the mailing list for the
patches adding bestcomm, ethernet and IDE support.  If you want to use
an arch/powerpc kernel, look at my tree on http://git.secretlab.ca.
The lite5200 branch already contains IDE, bestcomm, ethernet, PCI,
etc.

My tree works for me; but you'll need to update to a recent u-boot.
arch/powerpc requires passing in a flattened device tree at boot time.
 Look in arch/powerpc/boot/dts/lite5200b.dts for the device tree
source.  You'll also need to get the device tree compiler from
www.jdl.org.

Plus since Sylvain and I are actively working on this stuff; there's a
better chance that we can help.  :)

cheers,
