I only have the predecessor model (tibook 500), but can remember
similar problems.

I had to incorporate some of Charles Hannum's patches

  http://mail-index.netbsd.org/port-macppc/2001/09/30/0000.html

to get it working. Some of them got already imported, yet.

I also had to compile xkbcomp only with -O optimization; otherwise
dumps core...

If you like I can provide you my XFree86 binary (4.2.0) which is
currently running on my tibook.
