This is a bit of a late reply, but it appears that there is a 
reasonably inexpensive solution that I had not found when I 
originally replied to this message:

There are serial versions and ethernet-based versions.  The serial 
version looks simple enough even to connect to the console of a Cisco 
for remote access via a script, and the ethernet version doesn't 
appear too complex, either.  (Does a standard Cisco AUX port provide 
DTR power?)  The downside is that they're not SNMP-capable directly; 
an intermediate glue routine would need to be written.

You can find Nagios (a popular Open-Source monitoring platform) 
plug-ins for these devices here:
