Unity Greeter and Orca in Trisquel 7

When I installed and upgraded the Trisquel 7, made on July 9, I noticed
that Unity Greeter got installed. On reboot, after upgrade, I hit
'ctrl+s' and got, to my delight, a talking login dialogue. For the
moment, this key seems to act as a toggle, which is as it should be.
Should we make the live cd such that, if user does an accessible
installation, The login greeter talks on first boot? If we don't want
to do this, can we have a sound that plays to indicate when the greeter
is ready? Perhaps, it's time for a new "using Trisquel with Orca" type
wiki page?

Now, an observation:

When logging in with a talking session, one of my two Atom CPU cores was
loaded to 99%, and the other to about 30%. A fix for this seems to be
to kill all speech-dispatcher processes, and let the running orca
restart only as much as it needs. Now, both cores are at 29%, according
to system monitor. This is an Asus netbook with 1 GB ram and a
dual-core Atom.
