Summary css @font-face does not process SFNT bitmap ttf properly

I implemented an CSS @font-face rule in the following web page: http://wenq.org/unihan/kangxi_zh2.pl where the css file is located at http://wenq.org/webfont/wqy-bsong-13px.css It specified a truetype font (wqy-bsong-13px.ttf) to display Chinese characters. This truetype font is an SFNT wrapper of a single-strike bitmap font (at 10pt), i.e. a truetype font that has only embedded bitmaps. I created this font using FontForge, and it works fine with FreeType2, and can be properly opened in various font editing software (such as FontCreator and Fontforge). Expected results: all Chinese characters are displayed by the bitmap glyphs from this SFNT ttf font. Actual results: all Chinese characters are blank, seems webkit does not recognize the embedded bitmaps and try to use the blank vector glyphs instead.

one more comment on my motivation: as all of you know, Chinese (or CJK) fonts are huge, they can easily be over 10M in sizes, making it more difficult to embed in web pages. However, high quality Chinese screen display traditionally is achieved by embedding hand-tuned bitmaps. Creating a small truetype that uses only the hand-tuned bitmap seems to be a highly desired way of making Chinese (or CJK) webpages portable and viewed universally.
