No problem.

I have uploaded a patch to the bug tracker.  The difference between
baekmuk and daewoo is the xfont encoding registry.  Baekmuk has
ksx1001.1998 and daewoo has ksc5601.1987.  [xfonts-baekmuk package
installs also aliases with registry ksc5601.1987.]

Apart from the above temporary fix, another question is: I don't know
whether or not emacs is expected to slow down when it sees a font with
an unknown (to emacs) encoding.

Cheers,
Jae-hyeon
