Maybe it's not a problem related with a specific controller? I also have
the "unknown controller version" problem with my Dell Latitude E6510,
but it is a Ricoh controller:

$ lspci -vvvnn -s 04:00.1
04:00.1 SD Host controller [0805]: Ricoh Co Ltd Device [1180:e822] (rev 03) (prog-if 01)
        Subsystem: Dell Device [1028:040b]
        Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx-
        Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx-
        Latency: 0, Cache Line Size: 64 bytes
        Interrupt: pin B routed to IRQ 19
        Region 0: Memory at e5930000 (32-bit, non-prefetchable) [size=256]
        Capabilities: <access denied>
        Kernel driver in use: sdhci-pci
        Kernel modules: sdhci-pci

Though these bugs can be duplicates:

https://bugs.launchpad.net/ubuntu/+source/linux/+bug/474834
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/603445

My output is exactly like the last one. Also tested with kernel 2.6.33
but the problem remains.
