Addendum to addendum: the router fail is definitely caused by Tor connections filling up the router's ip_conntrack table - once it gets near full, it somehow interferes with a couple other services on my router (especially DNSmasq) even if there is free RAM. I will need to figure out some iptables tricks for the Pi, which I've long known, to prevent this, just no time yet.
Note that somehow, due to a brief enough hiccup I guess, my Pi relay retained Named, Stable and Fast this morning, so as soon as I restarted it it was instantly slammed with thousands of connections.
I may need to do the kludge of rate-limiting incoming connections to the Tor ports for now, using iptables.
Also of note: regarding the ntp and time/clock issue: it appears that because I was using a particular stripped image of Raspbian, some spurious .conf and init.d files were left for the Raspbian 'ntp' package, which I purged, and ensured that only 'ntpdate' (for setting the clock at startup, run in /etc/rc.local) and 'openntpd' are installed.

Addendum: restarting tor instantly puts my router into a tailspin this morning. This is a WRT54G (old school, 3.0 hardware, 200MHz MIPS). While that's old, there are many, many consumer routers out there with similar specs and worse firmware. In this case it causes major problems with DNS.
I'd like to figure out what is going on with this in order to prevent it from happening as part of the Cipollini project[1] so (when the time comes) we're not distributing images for Raspberry Pi which crash people's routers. :(
