Note that I'm using an EPIA ML, not an M board.

Maybe the EPIA-M HOWTO should tell that one needs to extract the VGA BIOS
from EPIA-M Bios Version 1.13 if one wants to use graphics on EPIA-ML.

Christian Sühs told on the list, that one needs an older vga bios for that.
First I will try to extract VGA Bios from BIOS 1.02 and 1.01 for the EPIA-ML.
Then I will try the BIOS 1.16 for the EPIA-M.
Unfortunately, VIA has taken all other versions off the web :(

Can I boot the EPIA-M Bios on the EPIA-ML board, or does it fail?

Disabling ACPI and AGPGART in the kernel fixed the problem,
so this was certainly an ACPI issue. Thanks to Anton Borisov.

Boot speeds is also an issue here, it looks like we need a separate
target/mainboard for the EPIA-ML in order to speed up the boot
process for EPIA-ML. It also boots very slowly here, I will try
Christian Sühs' changes discussed on this list in December 2005 
and disable some features (like smbus?) in the EPIA-ML boot process.

Obviously, EPIA-M and EPIA-ML have different features, compare them:
