I made a further attempt by following the http://www.mono-project.com/Mono:ARM
page with some changes for my situation.

Compile mono-20080110 on x86 Host.
  $ ./configure
  $ make
  $ make install DESTDIR=`pwd`/tmptree
Copy tmptree from Host to the Target filesystem

Compile mono-20080110 on ppc Target (instead of using scratchbox)
  $ ./configure --disable-mcs-build
  $ make
  $ make install

Looks good at this point on the ppc Target:
  $ /usr/local/bin/mono --version 

  Mono JIT compiler version 20080110 (tarball)

        Notifications: epoll
        Architecture:  ppc
        Disabled:      none

  $ mcs --version

  Mono C# compiler version 2008.110.0.0

It will run assemblies that were compiled on the x86 Host:
  $ mono HelloWorldHost.exe

  Hello Mono World (Compiled on Host)

It will NOT run assemblies compiled on the ppc Target:
  $ mcs HelloWorldTarget.cs
  $ mono HelloWorldTarget.exe

  Cannot open assembly HelloWorldTarget.exe.

Here are the first few lines with the verbose option:
  $ mono -v HelloWorldTarget.exe

  Method (wrapper runtime-invoke) System.Object:runtime_invoke_void_string
