Thanks Jukka, I didn't noticed the JPEG format. What I said is still true, but this should be the actual reason why OpenLayers shows a white background. You might even leave out the transparent option, since I assume OpenLayer uses transparent=true by default for WMS overlay layers (isBaseLayer=false).
