[plt-scheme] load-extension and modules?

Hello,

I have an extension "x.so" that defines a procedure, #<primitive:x>. I'd like to
use the extension in a module, eg.

(module m
  mzscheme
  (provide y)
  (load-extension "x.so")
  (define (y) (x 1)))

is this possible? With this example, I get

   STDIN::485: compile: unbound variable in module in: x

Thanks,
David Van Horn
