Yes, that is a source of problem; more obstacles, however, are waiting for us.
1.
To test an cid-keyed opentype fonts, I have copied *.cidmap files
into current directory and processed a simple document with luatex-plain.
But it did not work:
This is LuaTeX, Version beta-0.40.1-2009050920 (Web2C 7.5.7)
\write18 enabled.
(nanumotf.tex
(/media/disk/context/tex/texmf-context/tex/generic/context/luatex-basics.tex)
(/media/disk/context/tex/texmf-context/tex/generic/context/luatex-fonts.tex <lu
atex-fonts-merged.lua> <luatex-fonts.lua loaded in 0.027 seconds>)
(/media/disk/context/tex/texmf-context/tex/generic/context/luatex-mplib.tex)
LuaTeX warning: lua-loaded font [51] (/media/disk/context/tex/texmf-local/fonts
/opentype/korean/NanumGothic.otf) has no characters!
The same message as that of Li Yanrui's experiment, which would not
occur on windows machine. But I am on my linux box, whose
file system, as you know, distinguishs upper- and lower-case letters:
Adobe-Korea1-2.cidmap is quite different from adobe-korea1-2.cidmap.
So I added one line into luatex-fonts-merged.lua as follows:
--- ../tex/texmf-context/tex/generic/context/luatex-fonts-merged.lua
2009-05-12
18:29:55.000000000 +0900
+++ luatex-fonts-merged.lua 2009-05-13 01:14:55.000000000 +0900
@@ -3898,6 +3898,7 @@
local function locate(registry,ordering,supplement)
local filename = format(template,registry,ordering,supplement)

local cidmap = fonts.cid.map[filename]
if not cidmap then
if trace_loading then
2.
However, I still got an error even after that one-line patch:
This is LuaTeX, Version beta-0.40.1-2009050920 (Web2C 7.5.7)
\write18 enabled.
(nanumotf.tex
(/media/disk/context/tex/texmf-context/tex/generic/context/luatex-basics.tex)

atex-fonts-merged.lua> <luatex-fonts.lua loaded in 0.029 seconds>)
(/media/disk/context/tex/texmf-context/tex/generic/context/luatex-mplib.tex)
! LuaTeX error ./luatex-fonts-merged.lua:3879: attempt to call field 'loaddata'
(a nil value).
In other words, loaddata is not defined. So I issued "grep" command,
which helped me finding "io.loaddata" function defined in l-io.lua.
In sum:
even after modification of kpse, two more problems should be fixed.
1. lowering uppercase filename before searching cidmap
2. including l-io.lua into luatex-plain
