Same as any 603 with FPU.

You can't be mixing stuff like this.  If you would read the documentation
provided with the MontaVista CDK, you would have discovered that you
need to use the tools, libraries, applications, and file systems with
the kit.  Further, you would have discovered the 1.1 CDK is for an 8xx
and the libraries are compiled for soft (in-line) floating point.  You
are mixing floating point instructions with library and compiler support
that assumes otherwise.......The CDK 1.1 is an update to CDK 1.0.  The
documentation is found in the 1.0 directory.
