Chris,

>> That's the expected behaviour for fbdev since it does not wrap access to the framebuffer. 
Not getting the invalidate calls is expected?

>> Are you saying that you observe this after the display server is active?
Yes. Even when ubuntu Desktop is up, this behavior(absence of invalidate) is
observed.
