Okay, so do you think I need to take the device of the first sdhci =20
device or firewire's device like in the thread you mentioned?
I should then set the value to 0x20 I guess? Which address do I need to use?
FYI here is the pciconf -lv output with firewire and sdhci:
fwohci0@pci0:2:6:2: class=3D0x0c0010 card=3D0x30c3103c chip=3D0x08321180=

vendor =3D 'Ricoh Company, Ltd.'
device =3D 'unknown IEEE 1394 (4 pin firewire) chip)'
class =3D serial bus
subclass =3D FireWire

Yes, but without result.

Too bad...
