Comment 6 for bug 105180

I did not say that the feisty kernal did not support memory stick cards

I said the TIFM module doesn't (i.e the native driver for this reader)

As you seem unable todo any research (just looking at bug 53923) here is the FACTS from the tifm developer

Driver is implemented using several modules:

tifm_core - serves as "bus" driver for the adapters and cards
tifm_7xx1 - "host" adapter for the pci device in question
tifm_sd - driver for MMC/SD cards (registers itself as mmc_host under kernel's mmc subsystem)
Currently in development:

tifm_ms - driver for MemoryStick cards (very early alpha; does not work)
Pending implementation:

tifm_xd - driver for xD/SmartMedia cards

NOTE the tifm_ms driver is not present in the kernel.

Hence my coment to try the sdhci Driver because I believe that does support memmory sticks (Like you I haven't checked) but you need to switch the TIFM readers mode using setPCI and sdhci does not work for all TI hardware.

I checked the OP's logs and he is trying to use the TIFM module which does not support memmory sticks SO no bug.
