Success !
The key moves were disconnect keyboard and monitor first, connect to
Serial Port A and use the terminal to change default console to serial
port ("path con serial_A" command). With this configuration, all the
communication pass through to the Serial Port A and the Debian
installation runs clean and sweet.
Just to be clear for the next newbie, your Debian 8.0
_needs_internet_connection active to complete the installation The
c8000 built in Ethernet port is automatically configured with DHCP.
Hard disk partioning and formatting is also very smooth if you choose
the "easy" options (full disk,single partition).
As desktop, I choose Mate (I'm a Linux Mint fan).
I have rebooted the c8000 with a full HD monitor, keyboard and mouse
attached. With the serial terminal I have changed default console to
"graph3" (the AGP video card). Booting from the hard disk with Debian
installed open the classic login screen. The full HD monitor was
correctly detected and the resolution was the right one. Synaptic is
installed by defalt, so additional software installation is definetely
not an issue. Who said that Debian was difficult to install and
configure?
Sometime windows dragging and updating looks slow. No 2D acceleration,
frame buffer only? I don't know.
But the good news are not finished: installing "mesa-utils" I have
verified that 3D accelerated OpenGL is active and running (glxinfo is
OK and glxgears runs at 50 fps).
Thanks a lot for your very helpful guide to the installation process:

Linux Universe.
If you think useful, I'm available to write or update a wiki page for
Linux on the HP c8000. Otherwise, I will open a dedicated blog and
send you the link.

Now, I'm fighting with a very hardware issue: the screws of the PA
CPUs are non standard hex with a center pin. I hate this things.
Yesterday evening I was ready to upgrade from a single PA-8800/900 MHz
to a dual PA-8900/1GHz when I have discovered the screw issue. Today,
I'm going to go the Forge and build a "compatible" tool. Just for my
curiosity: "Have you found a compatible tool?".
Next episode: "For a fist of MIPS". "What happen when a quad-core HP
c8000 (2 x PA-8900, 1GHz) meets a quad-core Raspberry PI 3 (ARM
Cortex-A53, 1.2 GHz) ?"
