OK, I've answered the question myself. My Reliability Monitor is now
updating again and it's showing all data from Vista install (2/7/2007)
through yesterday (5/24/2007). To fix the problem, follow these steps:

1) Back up the files in the C:\ProgramData\Microsoft\RAC\PublishedData and
StateData directories
2) Empty both directories (i.e. deleted all the files in them). Note after
doing this Reliability Monitor puts up a text message in place of the
Stability Chart that says something to the effect that the data is missing or
corrupt.
3) Open a Command Prompt with elevated (Administrator) priveleges.
4) execute RACAgent at the prompt. Note that the task will run for a while
(several minutes on my system).
5) Open Reliability Monitor. Note that some or all of the Stability Chart
is back.
6) Check the "Last Updated:" date. If it's earlier than yesterday's date,
repeat step 4 and 5.

I had to run RACAgent 3 times to get it to work it's way through all the
data. It appears to process only a month's worth of data at a time.

This raises a number of interesting questions, e.g. where does RACAgent go
to find the data that it's processing and putting into the files stored in
the C:\ProgramData\Microsoft\RAC\PublishedData and StateData directories; why
does it only process one month's worth of data at a time; and assuming
RACAgent stopped working on my system because of corruption in these files,
what type of events can cause the corruption. I don't expect answers to
these questions of course - I'm just happy I managed to figure out how to
resurrect this important Vista feature. Hopefully future versions will be
more robust.
