Each time I boot seabios built with debug enabled,
I see this on serial console:
Scan for VGA option rom
WARNING! Found unaligned PCI rom (vd=1013:00b8)
Is this a bogus warning?

No. It's warning that your VGA ROM is broken and violates the spec by
having the PCIR table at a location which isn't a multiple of 4.
SeaBIOS loads it anyway, but we added the relatively harmless warning
after discovering that TianoCore refuses to do so.
Perhaps you are using a version of the VGA BIOS which still doesn't have
this fix applied:
