Remote machine: Assume Kindle appears as 192.168.2.1 on that machines network
Using a full copy of Netcat (nc) and assuming you haven't blocked new UDP connections in the Kindle's iptables setup (that is, open your above choice of port for UDP, state:new).
On Kindle:
(Listen, IPv4, re-start a new connection, no DNS lookups, UDP)
nc -l -4 -k -n -u 12345 >/proc/keypad
On remote machine:
echo "send 104" > nc -4 -n -u 192.168.2.1:12345
The Kindle end will auto-restart its listening for the next connection when it finishes receiving the above UDP packet.
I.E: You don't have to repeat the Kindle nc command, it will continue until you kill it.
Embellish as desired.
Such as start the Kindle nc command "on demand" using inetd and inetd.conf (in which case you don't need the "-k" - inetd will take care of start/stop of nc).

I seem to be having trouble, following my own directions.
Some versions don't know about -4/-6 (IPv4 / IPv6 selection).
Note: You can test the two nc ends by "talking" over the local-loopback (127.0.0.1)
No need to trash up your Kindle until you get what you want working locally.
