Okay, so do you think I need to take the device of the first sdhci  
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=0x0c0010 card=0x30c3103c chip=0x08321180  
rev=0x03 hdr=0x00
     vendor     = 'Ricoh Company, Ltd.'
     device     = 'unknown IEEE 1394 (4 pin firewire) chip)'
     class      = serial bus
     subclass   = FireWire
sdhci0@pci0:2:6:3:      class=0x080500 card=0x30c3103c chip=0x08221180  
rev=0x20 hdr=0x00
     vendor     = 'Ricoh Company, Ltd.'
     device     = 'R5C832, R5C843 SDA Standard Compliant SD Host Controller'
     class      = base peripheral
none2@pci0:2:6:4:       class=0x088000 card=0x30c3103c chip=0x08431180  
rev=0x10 hdr=0x00
     vendor     = 'Ricoh Company, Ltd.'
     device     = 'unknown Ricoh MMC Host Controller'
     class      = base peripheral

Yes, but without result.

Too bad...
