Hey there,
What you can do is define your HWPREDICT RRA in the gmetad.conf file to have
RRDtool collect that data. Then you can add if statements in the graph code to
draw the confidence bands and ticks as you like, for any metrics you want.
Please let me know if there is a better way to do this :P.

AFAIK there are currently no plans to add this to Ganglia, but we will
be more than happy to include this if a patch is submitted (or if one
of the developers take it upon him/herself to get this implemented).
But, thanks for pointing this out! Looks pretty useful.
Cheers,
Bernard
