Thanks for the info. By the way, I can still ping myself, which the DSL people said I shouldn't be able to do with it being fried, but hooking ethernet cables up to the now-working network or a proven-good crossover cable to another computer shows no connection.

All three devices are on surge suppressors. However, the telephone line is not. I have to assume that the spike came through the phone line and went from the DSL "modem" to the router to my computer. The lights didn't flicker or anything. I wouldn't know where to get a phone line surge suppressor (though, I vaguely remember seeing a power tree that had one built in); it would definitely be worth a purchase.
