Fabo...i have the sam problem as you, i also have the same chipset and memory:
Processor: ATJ2091
Memory: SAMSUNG 637, K9HAG08U1M, PCB0, CCGA75XA
...i can get it semi working with this dump file:
zany_dump.bin
but i only get the "hour-glass".
files seems to be missing in my dump, and i'm not sure what to add and how.
