Questions regarding LinuxPPC and Mot 860TFADS

I am trying to get the 2.2.5 (retrieved from the Linux embedded ftp
site) version of the kernel working with an 860T processor and the FADS
board. After reading much discussion on this list, I have the following
problems/questions.
I am compiling on a native LinuxPPC Mac. It is running 2.2.10. After a
few compiler problems early on, it compiles fine.
1) I've seen people being successful with an 823FADS board. Has ANYONE
ever gotten an 860TFADS running?!? If you have, what version of the
kernel are you using?
2) I am trying to mount an nfs root partition. I ran into the same
problems <tharvan at ellemedia.com> and <helmut.buchsbaum at siemens.at> did.
I put in the code for Helmut's fix. Then I encountered another
problem. (Helmut, you mention that you replaced the 'tlbia' instruction
with the tlbia macro. I assume that you did this in ALL places in the
code that uses tlbia? I tried it both ways (only in head.S and then
everywhere), but either way, I don't go any further.
3) I have tried in the init function SASH (as originally done in the
code), /bin/sh, and a couple of VERY simple (but not shell!) programs,
just to see if things would change. I continue to get a
bad_page_fault. I'll include a MASSIVE log of printks that I am trying
to use to find my problem, in case anybody can get any insight into this
problem.
4) I have been reading about CACHE LINE problems with Libc. Will these
problems be affecting me now at this stage (trying to get a shell
running)? It seems that others did NOT have this problem, or they would
have mentioned it.
Thanks for any suggestions and SORRY FOR THE HUGE LETTER!
I've included below my .config and printk dump.
