I think it could actually very well be an issue with the system libc/libresolv 
or equivalent.  On my Fedora Core 6 system (glibc 2.5) where it works:

$ host xn--fiqa61au8b7zsevnm8ak20mc4a87e.cn
xn--fiqa61au8b7zsevnm8ak20mc4a87e.cn has address 218.241.97.41
xn--fiqa61au8b7zsevnm8ak20mc4a87e.cn mail is handled by 10 
nm.xn--fiqa61au8b7zsevnm8ak20mc4a87e.cn.
$ ping xn--fiqa61au8b7zsevnm8ak20mc4a87e.cn
PING xn--fiqa61au8b7zsevnm8ak20mc4a87e.cn (218.241.97.41) 56(84) bytes of

On qa-dev where it doesn't:

$ host xn--fiqa61au8b7zsevnm8ak20mc4a87e.cn
xn--fiqa61au8b7zsevnm8ak20mc4a87e.cn mail is handled by 10 mail01.cnnic.cn.
