It did not detect the hardware on my Compaq 6910p:

none2 at pci0:2:6:3:	class=0x080500 card=0x30be103c chip=0x08221180
rev=0x20 hdr=0x00
    vendor     = 'Ricoh Company, Ltd.'
    device     = 'R5C832, R5C843 SDA Standard Compliant SD Host Controller'
    class      = base peripheral
none3 at pci0:2:6:4:	class=0x088000 card=0x30be103c chip=0x08431180
rev=0x10 hdr=0x00
    vendor     = 'Ricoh Company, Ltd.'
    device     = 'unknown Ricoh MMC Host Controller'
    class      = base peripheral

Suggestions are welcome. :-)

cd /usr/ports/sysutils/life
