I never managed to build working normal image for epia-m though. 
Fallback works fine, and vga bios too.
The only odd behaviour is that my epia-m2 has about 12sec delay before
it runs the coreboot image. 

here's my config.lb:
(57344 is my vga bios rom size)

------------------------------------------------------

target via_epia-m
mainboard via/epia-m
option MAXIMUM_CONSOLE_LOGLEVEL=8
option DEFAULT_CONSOLE_LOGLEVEL=8
option CONFIG_CONSOLE_SERIAL8250=1
option CONFIG_CONSOLE_VGA=1
option ROM_SIZE=0x40000-57344
option HAVE_OPTION_TABLE=1
option CONFIG_ROM_PAYLOAD=1
option HAVE_FALLBACK_BOOT=1
option CONFIG_COMPRESSED_PAYLOAD_NRV2B=0
option _RAMBASE=0x00004000
option FALLBACK_SIZE=0x40000-57344

romimage "fallback" 
	option USE_FALLBACK_IMAGE=1
	option ROM_IMAGE_SIZE=0x10000
	payload /boot/filo/filo.elf
end


buildrom ./coreboot.rom ROM_SIZE "fallback"
