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:
