found the problem - its my buggy vga.rom!!! it's missing the damn device_id!
ive patched it, and now the screen turns on upon boot, but no messages. however.... once i "modprobe i810fb" from the serial console, look and be-hold - we've got onboard-vga working! many thanks, now if we can figure out why it wont display upon bootup it will be great. also, another thing which troubles me - BEFORE booting begins, there are 0x00 sent to the serial for about 2 minutes (i've counted about 80 o those 0x00 being sent) and only then the coreboot messages starts to appear and the boot continues. i would appreciate eliminating this 2 minutes delay... any relevant information would be appreciated.
