Centrino duo, card reader and Linux

[Marcelo Magno T. Sales]

Hi,

I have a Centrino Duo notebook which has an embedded card reader (for memory 
sticks, SD cards, XD cards, etc.). No card inserted in the reader is detected 
by Fedora. I was hoping that the new F7 kernel would support it, but the 
reader is still dead after the upgrade.
lspci shows:

Is there anything I can do to get this device working? Or do I have to wait 
for a kernel that supports it?

Thanks,

Marcelo
