In my Alienware M17x there is a build in card reader for SD-Cards.
Currently I have no Idea why it doesn't work as I have used the new supplied driver in kernel 3.8. see lspci -v
Code:
13:00.0 Unassigned class [ff00]: Realtek Semiconductor Co., Ltd. RTS5209 PCI Express Card Reader (rev 01)
        Subsystem: Dell Device 0490
        Flags: bus master, fast devsel, latency 0, IRQ 41
        Memory at d3101000 (32-bit, non-prefetchable) [size=4K]
        Capabilities: [40] Power Management version 3
        Capabilities: [50] MSI: Enable+ Count=1/1 Maskable- 64bit+
        Capabilities: [70] Express Endpoint, MSI 00
        Capabilities: [100] Advanced Error Reporting
        Capabilities: [140] Device Serial Number 00-00-00-01-00-4c-e0-00
        Kernel driver in use: rtsx_pci

13:00.1 SD Host controller: Realtek Semiconductor Co., Ltd. RTS5209 PCI Express Card Reader (rev 01)
        Subsystem: Dell Device 0490
        Flags: bus master, fast devsel, latency 0, IRQ 16
        Memory at d3100000 (32-bit, non-prefetchable) [size=256]
        Capabilities: [80] Power Management version 3
        Capabilities: [90] MSI: Enable- Count=1/1 Maskable- 64bit+
        Capabilities: [b0] Express Endpoint, MSI 01
        Capabilities: [100] Advanced Error Reporting
        Capabilities: [140] Device Serial Number 00-00-00-01-00-4c-e0-00
        Kernel driver in use: sdhci-pci

dmesg seems to accept it too
Code:
[    0.854548] sdhci: Secure Digital Host Controller Interface driver
[    0.854632] sdhci: Copyright(c) Pierre Ossman
[    0.854718] sdhci-pci 0000:13:00.1: SDHCI controller found [10ec:5209] (rev 1)
[    0.854831] sdhci-pci 0000:13:00.1: Will use DMA mode even though HW doesn't fully claim to support it.
[    0.854952] sdhci-pci 0000:13:00.1: Will use DMA mode even though HW doesn't fully claim to support it.
[    0.879122] mmc0: SDHCI controller on PCI [0000:13:00.1] using DMA
Code:
[    0.737128] rtsx_pci 0000:13:00.0: irq 41 for MSI/MSI-X
[    0.737141] rtsx_pci 0000:13:00.0: rtsx_pci_acquire_irq: pcr->msi_en = 1, pci->irq = 41
But theres no useable blockdevice, dolphin is missing the device when a sd-card is used.
The kerneldriver lists my RTS5209 and an usb-adapter for sd-cards is functional.
Do you have any idea where to look next?

Never used rts_bpp, but I hope it is the same and gets fixed :-(

edith: mine was CONFIG_RTS_PSTOR
But thank you, now I know I might be not alone.

Googling around I found this.

We need to make sure our kernel has:

Code:

CONFIG_MFD_RTSX_PCI=m
CONFIG_MMC_REALTEK_PCI=m
CONFIG_MEMSTICK_REALTEK_PCI=m
MMC_REALTEK_PCI=m
MEMSTICK_REALTEK_PCI=m


And now my card reader is working as it should.
