Hi Arnaud,

I don't know what would cause this.  A couple of guesses:

* coreboot isn't setting up the pci space with the correct legacy
  ranges

* seabios isn't implementing some bios feature the card is expecting

Because you're seeing this on two completely different vga cards, I'd
guess that it's something with the coreboot pci setup.  I'm not
familiar with Club3D - can you verify it isn't also using a Matrox
chip?
