First of all, please avoid HTML in e-mail messages. It is hard to read, and 
normally banned on mailing list such as this one.

Yes, MPC852T is supported, although I might add that I have been using 2.6.14 
and 2.6.15 sucessfully with our own MPC852T-based board, but 2.6.16 did not 
boot and as of today I don't know why, or whether this is an issue at all 
with boards other than ours.

Yes. Look at BSP stuff for other 8xx boards to learn how to port yours. Keep 
an eye on the new platform_bus stuff, that's currently being implemented for 
different drivers and subsystmes for powerpc (this could be the reason, our 
own BSP stuff stopped working with 2.6.16, btw).
Also a transition from /arch/ppc and /arch/ppc64 towards the 
common /arch/powerpc is in progress, and therefore some things might be in a 
state of flux between released versions of the kernel. As of today (kernel 
2.6.16) the architecture you need to use is still /arch/ppc.
Good luck!
