No video memory. no memory acceleration for Intel HD graphics. what now?

Question

I did a quick double buffering on my pc with a Intel HD graphics (integrated with CPU) and works fine but jumpy and flickering a little. I run a check on the BufferedStrategy, BufferCapability and ImageCapability (code below), and found that no video memory, image cannot be accelearated in any way and Java is using blitting to do the double buffering.
Is this normal for Intel HD graphics or my program is flawed anywhere?

}Without video memory, how do I create smooth animation? My pc is a Xeon 3.0 Ghz computer with 4GB memory.

If you're looking to discuss this matter I would advise you to take it to java-gaming.org; people there deal with this stuff on a daily basis.
