First things first - apparently your tun module is compiled for the
different kernel that you run. Good, stock in-tree kernel modules do
not have unresolved symbols.
Second, on my system tun.ko definitely references
"ipv6_proxy_select_ident kernel" symbol. Which can only lead to suspect
the kernel.
Third thing is - unless you manage to convince tun module to load -
openvpn won't function.
Hence, the questions are:
1) Are you using stock/backported Debian kernel on VPS?
2) Have you upgraded the kernel since openvpn worked for you?
3) Any reboots since then?
