Internal card reader on HP 2510 p

Intro

The only "nice to have" thing on the mentioned above laptop, what wasn't working out of the box (with Kubuntu 2008.04 since beta, kernel 2.6.24) was the SD and MM card reader.
lspci told me this:
02:06.0 CardBus bridge: Ricoh Co Ltd RL5c476 II (rev ba) 02:06.1 FireWire (IEEE 1394): Ricoh Co Ltd R5C832 IEEE 1394 Controller (rev ff) 02:06.2 SD Host controller: Ricoh Co Ltd R5C822 SD/SDIO/MMC/MS/MSPro Host Adapter (rev 21) 02:06.3 System peripheral: Ricoh Co Ltd R5C843 MMC Host Controller (rev ff)

Some dmesg output on loading the needed modules (sdhci, ricoh-mmc, mmc-block etc.) told, that the hardware is present and identified by modules, but there was no reaction, if I've inserted a card (SD or MMC). Manual mounting was not possible too, because there was no device.

Investigation

From time to time I've tried some sources about this (or not this) issue:

But without success... Then I've found some words about the newest change in the kernel 2.6.25:

http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=882c49164d72c45f37d7fa1bb3de7c31cf1a5fab

The next important step was to try openSuse 11 beta live - everything was working out of the box!!!
