this is really great news !

That's correct (the only exception is the kernel from Red Hat 9).

What are these problems ?

I'm sure I can help here fixing these bugs.

Well, some time ago I was thinking myself about some kind of a proxy
program for the debugger to communicate with MonoDevelop - it's really
cool to see that you've written one :-)

Sure we can make changes and fix problems in the debugger, let's just
discuss what you need.
