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.

perhap loading by default pci hotplug and do a rescan every second ?

can you post full boot log with pci debug enabled?

CONFIG_PCI_DEBUG=y

and "debug ignore_loglevel" in boot command line.

also post:
lspci -tv
lspci -vvxxx
lspci

should have one booted with card inserted and one booted without card inserted.
