We specialize in coreboot related questions, so it's unlikely we can help you with a BIOS problem unless you want to replace that BIOS with coreboot. > I'm developing a little hardware module with a w83627hf superio module. > This hardware is attached to a com express module.

Make sure the w83627hf kernel module is not loaded automatically, then run superiotool -dV and compare the outputs. If superiotool finds your SuperIO only on one of the boards, you most likely have a southbridge resource configuration problem which needs to be addresses by the BIOS manufacturer (or a custom early kernel driver). If superiotool finds your SuperIO on both boards, compare the settings and work from there.
