It appears that RTEMS has been ported to the RasPi

Interesting!
I'm not clear whether this runs on bare metal?
Did you know that Rasbian (Debian wheezy) provides Ada already? (your
Subject implies not).

No. RTEMS is a RTOS, so you write to the RTEMS API, not the underlying
bare metal.
However, RTEMS is very lightweight when compared to Linux so it can
run (with a appropriate BSP) on a lot more platforms than Linux can;
it doesn't even need or really use a MMU (other than a optional initial
setup, which is a BSP specific not RTEMS specific function).

Sorry, I wasn't clear.
What I meant was, does the port of RTEMS to the Pi include a BSP so that
applications built to RTEMS can run on the bare Pi?
And on re-reading the link, I see that it does[1], though only the timer
and the UART are supported so far.
