SubjectRe: Is the Ricoh R5C822 documentation available?

Weird. My laptop has the same device and I've successfully installed
Debian to it [1]...

02:06.2 SD Host controller [0805]: Ricoh Co Ltd R5C822
SD/SDIO/MMC/MS/MSPro Host Adapter [1180:0822] (rev 21)
Kernel driver in use: sdhci-pci
Kernel modules: sdhci-pci
02:06.3 System peripheral [0880]: Ricoh Co Ltd R5C843 MMC Host Controller
[1180:0843] (rev ff)
Kernel driver in use: ricoh-mmc
Kernel modules: ricoh_mmc

The function of the ricoh_mmc module is to disable the last (proprietary)
controller in favor of the first (generic) one.

Cheers,
FJP

[1] Installing to SD/MMC card is supported as of D-I Lenny RC1 for i386
and amd64.
