Comment 1 for bug 63121

1. There seems to be missing entry in /etc/udev/rules.d/40-permissions.rules. Hotpluggable devices seems to have group set to plugdev, so I think there should be line like this (like one for usb devices):
BUS=="mmc", GROUP="plugdev"

2. When running lshal --monitor and inserting/removing card I can see such entries:

Start monitoring devicelist:
-------------------------------------------------
pci_104c_8033 property info.linux.driver = 'tifm_sd'
pci_104c_8033_mmc_host added
pci_104c_8033_mmc_host_mmc_card_rca56096 added
pci_104c_8033_mmc_host_mmc_card_rca56096_storage added volume_uuid_1C47_7969 added
volume_uuid_1C47_7969 removed
pci_104c_8033_mmc_host_mmc_card_rca56096 removed
pci_104c_8033_mmc_host removed
pci_104c_8033_mmc_host_mmc_card_rca56096_storage removed

So it seems that hal has full info about device, it assigns volume_uuid and the only thing missing is to "pop-up" icon on the desktop.
