Выяснилось, что виноват сам ping, т.к. простейшая программка на С, 
использующая gethostbyname, адреса вполне себе разрешает.

Полный вывод strace -f ping test в аттаче. Мне непонятен следующий фрагмент:

chroot("/var/resolv")                   = 0
chdir("/")                              = 0
setgid32(101)                           = 0
setuid32(100)                           = 0
open("/dev/urandom", O_RDONLY)          = -1 ENOENT (No such file or 
directory)
getpid()                                = 2824
getppid()                               = 2823
gettimeofday({1143540140, 102722}, NULL) = 0
getpid()                                = 2824
open("/dev/urandom", O_RDONLY)          = -1 ENOENT (No such file or 
directory)
times({tms_utime=0, tms_stime=0, tms_cutime=0, tms_cstime=0}) = 1718341389
open("/etc/resolv.conf", O_RDONLY)      = -1 EACCES (Permission denied)

Ну ладно, /dev/urandom в чруте действительно отсутствует, но 
/etc/resolv.conf на месте и с нормальными правами:

В чем тогда дело?
