Hi Hans,
I tried to use Chinese opentype fonts with luatex + plain fmt but I
failed. Only with Chinese TTF fonts it can work.
This a simple example:
\pdfoutput=1
\font\myfont=AdobeSongStd-Light
\myfont
我想实现 LuaTeX 对中文的支持
\end
When I compiled it, I got the following messages:

this is because a cidmap is needed and the kpse that you use does not have
it; upcoming versions of kpse (and luatex's kpse lib) will support it given
that you also adapted your texmf.cnf accordingly then
so a bit patience is needed
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:

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

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

! 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
