PPoE link dropping and occasionally failing to reconnect

[Myk]

I am using my Almond Plus to connect via a PPoE wireless broadband connection. My connection drops out frequently and when I turn on logging on the PPP daemon, I see this

So it looks like there's a problem with the current libcrypt on my AlmondPlus, possibly making GRE not work?
The PPTP howto http://pptpclient.sourceforge.net/howto-diagnosis.phtml#gre needs me to use tcpdump, which isn't available on the AlmondPlus, so my ability to troubleshoot this has hit a brick wall.
