With fare's code I booted (well, not completely), it says RAM
is at c000.0000 and it's 16MB.

Physical, I think.

I got this printed by hpcboot. I think they are the LCD registers but
I didn't check yet:

   Display: 640x480 8bpp
   Reg0 :4401a119
   Reg1 :c007327f
   Reg2 :c007327f
   Reg3 :00000001
   Reg5 :c0073007
   Reg6 :000b0020
   Reg13:0c000000
   Reg14:63a531e2
   CPSR :600000df

I think we can probe a lot from within hpcboot or blob.

Isn't it connected always in the same way?

/me is naive enough on this, with a lot of paper to read :)
