shifted the tree to etch. filo-0.5 compiles. But...

./buildrom coreboot.strip coreboot.rom payload 0x10000 0x20000
ERROR: payload (78064) + coreboot (65536) - Size is 12528 bytes larger 
than ROM size (131072).
make[1]: *** [coreboot.rom] Error 1

since 
vgarom = 61952 
payload = 78064
coreboot = 65536
total = 205552

It should fit into the 256KB flash with 56592 bytes to spare.

Do i need to disable fallback?
What is the purpose of fallback.
