Very interesting...

http://www.mikrocontroller.net/t...

Author says that 64K SRAM must be at least 55ns. I have access only to 128K SRAM 70ns (628128LP-70). Could it work?

The spec of 55nS is mentioned for a reason! Using a slower part (70nS) will most likely work - but if it fails when cold/hot then don't be surprised! The failure will be seen as pixels not the right color and randomness. You might look for old PC motherboards for suitable high speed ram.
