thats not what I mean.. what I want is something like

if (function_present(foo))
   x = foo();
else
   x = SAFE_VALUE;

use x somehow;

so we don't have to have all modules loaded etc. the same could be done
for some syscalls, imagine

linux_foo(params)
{
   if (function_present(foo))
      return foo(params);
  else 
      return ENOSYS;
}

I like this better then loading all possible modules.
