This seems to work, at least in irb:

irb(main):001:0> class WarningException < Exception; end
irb(main):002:0> module Kernel
irb(main):003:1>   def warn(m)
irb(main):004:2>     raise WarningException, m
irb(main):005:2>   end
irb(main):006:1> end
irb(main):007:0> warn "Hello"
(irb):4:in `warn': Hello (WarningException)
        from (irb):7:in `irb_binding'
        from C:/Apps/Ruby18/lib/ruby/1.8/irb/workspace.rb:52:in 
`irb_binding'
        from C:/Apps/Ruby18/lib/ruby/1.8/irb/workspace.rb:52

This, of course, depends on the module using the <warn> functionality. It 
also won't work on rb_warning or rb_warn, obviously.
