I also followed the above blog directions from http://intr.overt.org/blog/?p=59
They worked fro a Dell Inspiron 6400.

This is the PCI device i changed below with the setpci command
03:01.0 FireWire (IEEE 1394): Ricoh Co Ltd R5C832 IEEE 1394 Controller

setpci -s '03:01.0' 0xCA=0x57 #enables you to write to the device
setpci -s '03:01.0' 0xCB=0x02 #set register to disable MMC
setpci -s '03:01.0' 0xCA=0x00 #disables write to device

Now I can read and write MMC cards.
