What methods do people use to notify users of upcoming downtime in an
application, and for handling requests nicely while scheduled downtime
is occurring? My Google-fu is not yielding me anything useful-looking.

Depends, the easiest way is to use capistrano:
http://www.google.be/search?q=capistrano+maintenance+page
It will put a maintenance page in the public folder for the time that
your app is offline.
There’s other ways to do it, like handling it in Apache itself if
you’re using Mongrel cluster, like checking if the mongrels are up and
if they’re not, serve a custom error page.

And concerning the notification, it’s all up to what you personally
prefer tbh. One way to go about it is create a Downtime model and with
a start and end time, put a before_filter in application_controller.rb
that fetches all those > Time.now, then show them by rendering a
partial into every view if the number of records is higher than one.

I was contemplating methods of easily having a pop-up or banner to say
“the site is going down in ten minutes”. That sounds like a nice
reusable one.

We use comatose to manually post a very visible notice about any
scheduled maintenance…
and for handling requests nicely while scheduled downtime
is occurring?
… though we have 2 load-balanced servers, so generally we can get
away with updating stuff invisibly
