[Arm-netbook] CT-PC89E SO-DIMM pinout progress: 20% mark reached

[Luke Kenneth Casson Leighton]

good news: after only 2 days with a multimeter i have reached the 20%
mark already.  i now have the 16 LVDS data lines, CLKIN and SHTDN; the
right-hand GL850G USB2; i've established that the left-hand GL850G is
chained to the right-hand one; i have the DEP9000's 16 data lines, and
enough ground and power pins to take that up to around 40 pins.  that
makes it about the 20% mark.

to get the full complement, i will need a pair of break-out boards,
with 200 wires between them!  a socket that is connected by 200 wires
to a "blank" SO-DIMM, where i can then connect the oscilloscope _live_
to pins, without damaging the SO-DIMM or the motherboard.  i _could_
solder 200 individual wires directly to the motherboard, but i would
have to be off my head to do that, running 100 tiny wires out from
underneath the SO-DIMM.

but, with a breakout board, it will be possible to determine the
functionality of the remaining pins which are *not* connected on the
CT-PC89E, for example if they are connected to "unused" GPIOs.  it
will be possible to write a simple app which pokes directly into
/dev/kmem at the S3C GPIO registers (i know, i know)

i am slightly at a loss on how to determine what the address bus is,
for the DEP9000.  i have the 16 data lines.

anyone got any clues (ben?)
