Thanks guys, after a little fussing I think I got it working. I do see
/var/lib/ampr-ripd/encap.txt filling full of routes, so I think that
that means it's functioning correctly.

This is what I have now. I post this so you if anyone spots anything
stupid, they can let me know.
sysctl -w net.ipv4.ip_forward=1
modprobe ipip
ip addr add 44.4.28.50/32 dev tunl0
ip tunnel change ttl 64 mode ipip tunl0
ip link set dev tunl0 up
ifconfig tunl0 mtu 1480
ip rule add from 44.4.28.50/32 table 44 priority 45
ip rule add to 44.0.0.0/8 table 44 priority 44
ip route add default dev tunl0 via 169.228.34.84 onlink table 44
ip route add 44.4.28.50/32 dev tunl0 table 44
ip route add 44.0.0.0/8 via 44.4.28.50 dev tunl0
iptables -A INPUT -p 4 -j ACCEPT
iptables -A INPUT -p udp --dport 520 -j ACCEPT
ampr-ripd -s -r -t 44 -i tunl0 -a 44.4.28.50/32
