Default Using SD-card reader? (Lenovo T61/Richo R5C822 controller/sdhci driver)


I'm trying to access an SD-card using the built-in reader on a Lenovo
T61 Laptop running CentOS 5.7. The unit is recognised by lspci:
# lspci
[ ... ]
15:00.2 SD Host controller: Ricoh Co Ltd R5C822 SD/SDIO/MMC/MS/MSPro
Host Adapter (rev 21)
15:00.3 System peripheral: Ricoh Co Ltd R5C843 MMC Host Controller (rev 11)
15:00.4 System peripheral: Ricoh Co Ltd R5C592 Memory Stick Bus Host
Adapter (rev 11)
15:00.5 System peripheral: Ricoh Co Ltd xD-Picture Card Controller (rev 11)

and a driver is loaded and appears to find the device - from

Oct 13 09:30:48 i58524 kernel: sdhci: Secure Digital Host Controller
Interface driver, 0.12
Oct 13 09:30:48 i58524 kernel: sdhci: Copyright(c) Pierre Ossman
Oct 13 09:30:48 i58524 kernel: sdhci: SDHCI controller found at
0000:15:00.2 [1180:0822] (rev 21)
Oct 13 09:30:48 i58524 kernel: ACPI: PCI Interrupt 0000:15:00.2[C] ->
GSI 18 (level, low) -> IRQ 225
Oct 13 09:30:48 i58524 kernel: mmc0: SDHCI at 0xf8101800 irq 225 DMA

But then what?? If I insert a card in the drive, nothing particular
happens. I mean, I the status LED on the unit lights up briefly, but
there is no automount or anything, and I get no messages in the system
log. And I can't find any appropriate devices under /dev. The card is
accessible when using WinXP on the same machine...

Help, anyone?
