This sounds about right. On a device like the G1 or HTC Magic (which are more or less equivalent to the HTC Hero) it takes about 4 ms to draw a full screen opaque image. In your case you are drawing two images and the second one is twice as big *and* requires blending, which is done in software. 30 fps seems about right, you're limited by the hardware.
