A suggestion on the current http://i.imgur.com/oRtAm9f.png
Reduce the unused area, by making a cutout in the final pcb,
the purpose of which is to reduce any chance that the pcb will
intrude onto or close to motherboard components (capacitor tops,
insertable bios ROM, coils, etc.). {So reduces likelihood of;
"Gee - I would have preferred to place the card in ISA slot N,
but there was a tall component blocking the overhang there so
I had to put the card in a less desired slot..." 😢 }.
A cutout will also act to usefully provide additional separation
of the pcb planes from any RF emitted by various motherboard
components. (Orange or grey line shows cutout area, below left;)
The attachment oRtAm9f-mobo clearance.png is no longer available
If the fabrication company cannot action the cutout without
undesireably adding to the price, perhaps a line of through
holes nearly touching each other, would serve as a last ditch
option allowing someone to gently connect (saw through) the
holes, so as to clear any obstacle, if it turns out that your
preferred motherboard, (perhaps with only one ISA slot) won't
allow fitment of the length of the pcb... .

Another suggestion; include a slight vertical separation between
each horizontal set of jumpers for each of banks 0, 1, 2 and 3. (JP7)
The reason is so that each horizontal jumper will still be able to be set
'as desired' for each individual bank - BUT with the vertical separation
of each set of bank jumpers, you ensure that there is no possibility
of a user accidently placing a jumper joiner which joins (vertically) pins
of any bank - this could conceivably cause damage to the ram (say, for
instance, that bank 0 and 1 highside potential pins {each leftmost pin? of
bank 0 and 1} were inappropriately joined by a jumper placed accidently
vertically across those two pins).

ROLL ON THE 'GUSONAISSANCE' !!
