Ok, I've hacked a bit on the input drivers (trying to look at the
differences between the pc_keyb.c and the new initialisation sequences),
with some limited success.

What I found out is that the mouse is not responding to any of
the commands in psmouse.c:psmouse_probe. However, if I comment out
the 'return -1' statements from this function, the mouse will
be recognised as a default PS/2 mouse. 

Later, in psmouse_initialise, the PSMOUSE_CMD_ENABLE will fail too
(no response from the mouse). But since the error is not propagated
to serio the device remains registered.

And later, the mouse will get enabled somehow and will function
perfectly. I didn't succed in finding out what exactly enables it,
even if I strongly suspect some interraction between the keyboard
enable and aux port enable... 

Any further idea ?

What I also did, maybe you'll find this interesting, is recording 
the events sent by the pc_keyb.c driver to the i8042 port (by tracing
the inb/outb in include/asm-i386/keyboard.h):
