Karl,
can you update the dvipdfmx stuff to the current CVS version? It
contains a very important improvement for my CJK package, namely to
use a cmap file `foo.cmap' (for ToUnicode mapping) for a font
`foo.tfm' -- since the CJK fonts in TeXLive are splitted into Type 1
subfonts, this greatly simplifies the process to get proper ToUnicode
mappings.
