I'm not sure there's anything I (at the MMC layer) can do to help; having a visible PCI device is a prerequisite for working MMC.

Have you tried a recent upstream kernel, and looked for any available BIOS updates for your laptop?

Thanks,

BIOS is lasted and kernel is 3.1.

I know that  PCI device is a prerequisite  but I believe it is possible to run some quirk on this laptop, in order to get the mmc reader up earlier.
