When you print the SVG to file (in PostScript format, using Inkscape's print dialog), is the content of the PS file also rasterized? Maybe it's an issue with the driver not handling Inkscape's PostScript output correctly?
Printing the file to PostScript with Inkscape 0.48 on OS X 10.5.8 does not rasterize the content - the PostScript file contains only vector information.
