It failed because it was using the wrong version of "resgen".  It looks like 
it accidentally found Mono's version instead of pnet's.  You will need to 
reconfigure pnetlib and make sure that it finds the right one this time.  The 
"--with-pnet" option should not be the install location, but rather the 
actual source tree, including compiled binaries, of the i386 version.  i.e. 
the directory where you compiled it.  If you are still having problems, then 
set the RESGEN environment variable to point to the pnet version.

When compiling pnetlib, you may want to also set up for C cross-compilation, 
as you did with pnet.  This should cause it to generate the correct 
libXsharpSupport.so and other platform-specific files.

Not that I am aware of.  However, frame buffer access is pretty low level.  
You would need to build a lot of fundamental window and drawing 
infrastructure by hand.  I suggest using an embedded GUI toolkit like 
Qt/Embedded, gtk, or SDL to provide the fundamentals.  There are embedded 
versions of X as well, which should make the port relatively trivial.

Without libgc or libffi, pnet won't be terribly useful.  You'll need to figure 
out how to port them also.  In particular, the WinForms library requires 
PInvoke, which is dependent upon libffi.
