Hello,

  Thanks a lot Manan ! That worked indeed, here are the commands I run:

sudo setpci -s 07:05.1 0xCA=0x57 # Write Enable
sudo setpci -s 07:05.1 0xCB=0x02 # (MMC Disable)
sudo setpci -s 07:05.1 0xCA=0x00 # (Write Disable)

Actually the first two commands alone were enough to make my MMC card
work ! I don't know what the third commad is for, but I included it
since it was on the site Manan quoted.

Note, the slot '07:05.1' may differ on your machine.
