You almost got it:

bundle agent conf_system_syslog
{
vars:

ipv4_192_168_235::
"syslog_host" string => "192.167.235.34";

ipv4_192_168_5::
"syslog_host" string => "192.167.5.12" ;

files:
  "/etc/syslog.conf"
    edit_line => sysklog_config;
}

bundle edit_line sysklog_config
{
insert_lines:
redhat_5&!cpp_syslog_host::

"*.info;mail.none;authpriv.none;cron.none @$(syslog_host)";
}


I made syslog_host a string rather than a list, and then it can be directly 
used in the string you insert in the configuration file.

Note that if syslog_host changes, then the promise will insert a new line into 
the file, rather than editing the existing one. For this you could use 
something like set_config_values: https://gist.github.com/548981 , with 
something like this:



bundle agent conf_system_syslog
{
vars:

ipv4_192_168_235::
"syslog_conf[*.info;mail.none;authpriv.none;cron.none]" string => 
"192.167.235.34";

ipv4_192_168_5::
"syslog_conf[*.info;mail.none;authpriv.none;cron.none]" string => 
"192.167.5.12" ;

files:
  "/etc/syslog.conf"
    edit_line => set_config_values("conf_system_syslog.syslog_conf");
}
