can't read from a Ricoh SD (Secure Digital) card reader

[Tim]

I have an Asus PRO31J F3JC laptop with a Ricoh SD card reader that
Fedora is slightly aware that it's in the computer, but doesn't actually
do anything with it.  I gave Ubuntu (7.10) a try last night, and it can
read from the card.  I know little about Ubuntu, other than it being
Debian in disguise (and I've never used Debian), to know whether we can
purloin anything from it to use with Fedora.  Does anybody know if we
can?

Fedora's lspci|grep Ricoh output:
06:01.0 FireWire (IEEE 1394): Ricoh Co Ltd R5C832 IEEE 1394 Controller
06:01.1 Generic system peripheral [0805]: Ricoh Co Ltd R5C822 SD/SDIO/MMC/MS/MSPro Host Adapter (rev 19)
06:01.2 System peripheral: Ricoh Co Ltd Unknown device 0843 (rev 01)
06:01.3 System peripheral: Ricoh Co Ltd R5C592 Memory Stick Bus Host Adapter (rev 0a)

Ubuntu's lspci|grep Ricoh output:
Fedora's lspci|grep Ricoh output:

Yes, the in-built card read is a PCI device.  And, yes, I can read my SD
cards using an external USB adaptor, but it's not convenient having
things hanging out of the laptop.  No, I can't add a PCMCIA card reader,
the laptop has an ExpressCard slot, instead, and I've not seen anybody
selling those, nor do I know if they'll be supported.
