For which version of FreeBSD is it? I'm running RELENG_6 on my notebook, which has two such slots (one for SD cards and one Sony memory sticks). If your driver works on RELENG_6, I can try it when I have some free time. none3@pci6:9:2: class=0x080500 card=0xc01a144d chip=0x08221180 rev=0x17 hdr=0x00 vendor = 'Ricoh Co Ltd' device = 'SD Bus Host Adapter' class = base peripheral none4@pci6:9:3: class=0x088000 card=0xc01a144d chip=0x05921180 rev=0x08 hdr=0x00 vendor = 'Ricoh Co Ltd' device = 'Memory Stick Bus Host Adapter' class = base peripheral It's a Samsung X20-XVM 1600-V notebook (Pentium-M / Centrino with i915 chipset). I like it very much, because all of the components are supported by FreeBSD, except for the SD and memory stick slots. I don't have any memory sticks, so I don't care, but I do have an SD card which I use with my Zaurus PDA (running Linux), and it would be very nice to access it directly with the notebook, without having to use a USB cardreader.
