Ricoh SD card reader

Ricoh SD card reader

[Herman Sheremetyev]

Hi All,

I'm hoping I'm on the right list with this question, if not please
accept my apologies and if possible direct me to the right place. I own
an Asus M6N series notebook that has a built-in SD card reader that I'm
trying to get working.  I'm running Fedora Core 2 with a vanilla 2.6.7
kernel and pcmcia-cs-3.2.7.  Reading through the pcmcia-cs docs it seems
that my chip is supported my the memory-cs module however all memory
support is removed from the RPM with a comment saying that it's obsolete
and should be handled by MTD drivers in the kernel.  The pcmcia-cs docs
also state that I can't use the standalone drivers with a 2.6 kernel so
I'm out of luck testing that module.  I read through the available
documentation on MTD that comes with the kernel and tried loading the
various mtd modules but nothing seems to work.  Here's some information
about the device:

None of the other MTD modules produce interesting output.  Any
assistance would be much appreciated.

TIA,
