Have you considered getting the client to do the work? You could write a webpage that uses two images and javascript or DHTML.
The first image would comprise the gauge with values, the second a needle or pointer with a transparent background. Overlay the two images, use javascript to rotate the pointer image. When the page is called insert the raw values somewhere in the page. The javascript could then convert the value to an angle and rotate the pointer the desired amount. If you reuse the pointer you could get away with using only seven images. (Pointer and six dials) The HTML page would have to be created on the fly, which is an added load, but this may still prove to be less demanding than the creation of an image on the fly. If you move the javascript to a .js file the client browser may pull the javascript from cache, further reducing the work the NSLU2 has to do. Google gave me this: http://www.walterzorn.com/rotate_img/rotate_img.htm - The first item on the page looks promising.
