Dear SeaBIOS folks,
testing QEMU with coreboot built from commit a296f9e3 (Kconfig: Allow native vga init to be selectable for SeaBIOS payload) [1] and SeaBIOS and SeaVGABIOS (selected in coreboot’s Payload menu), SeaBIOS does not display any graphics although the console says, it has initialized it.

$ qemu-system-i386 -bios build/coreboot.rom -hda /dev/zero -serial stdio […] Scan for VGA option rom Running option rom at c000:0003 pmm call arg1=0 Running option rom at c980:0003 Start SeaVGABIOS (version rel-1.7.5-0-ge51488c-20141004_165959-my-qemu-system)
Note the above shows that two vga option roms got executed. One was the onboard vga rom that QEMU provides, and the second was seavgabios.
Try adding "-device cirrus-vga,romfile=" to your qemu command line to force qemu to not provide an option rom in the vga pci rom bar.
