yes i added this line and it seems that i need also  add:
default CONFIG_VGA_ROM_RUN = 1
to the Options.lb file, without this it doesn't work.
I needed  also this patch:

The console is turning on
when the linux is starting (not at the FILO start)

the e-Vectra has no  additional slots on board , therefor it has only an
onboard vga card.

sounds great.

the bios size is 512KB - really :-)
the vga bios size is 32KB
it has also an ethernet bios inside the bios (size 58880B)

ok, I will try to make the tests tomorrow.
