We've finally been able to obtain better fonts for the new characters in CJK-Extension B. The PDF chart is at http://www.unicode.org/charts/PDF/U20000.pdf.
Enjoy. A./ PS: Fair warning: the complete PDF file is 13MB and contains only the glyph and code point, no other information about the character. If you just want to look up an isolated character, the Unihan database is a much better bet ;-)
