Hi.
I would like to present initial revision of my generic PCI SD Host Controller driver (sdhci). It support PCI devices with class 8 and subclass 5 according to SD Host Controller Specification. With some limitations it successfully works on my Acer TM6292 notebook with ENE CB714 card reader.
Things that are not working yet: - DMA modes (code is written, but as my controller looks like has broken DMA I have no ability to debug it), - card insert/remove detection (need more thinking), you should reload mmc module to rescan cards, - SDHC and MMC cards (have no such cards now to debug that code), only standard capacity SD Memory cards up to 4GB size are supported now, - high speed (double rate) bus mode (need more thinking and DMA support).
Most 4G cards are SDHC that I've seen. The notes on this that I've read talk about the fact that you can have a 4G regular SD card but that many (most) devices don't support it because of the need for a larger FAT to support 4G.
s/many/a few/g. 4GB SD cards work fine in every device I've tried them in...
You are quite lucky then. 4G-SD are non standard and I have a few devices where they don't work with. Sadly I even own a USB reader, which is still being sold, that doen't work with 2G cards - it just truncates them at 1G - sigh.
