So, I had a need to use my SDHC card in my Dell Studio 17 (1737) notebook. So, I set out to find out why it wasn't working. I ended up finding out that I needed to load mmc_block and sdhci-pci in order to get it to work. Here's what I did.
So, I couldn't figure out how to get my Macbook function keys to default to function keys under Linux, rather than media keys such as brightness, volume control, etc. I searched all over the net for information on this feature, and could only find stuff about pb_fnmode (which doesn't appear in the latest kernels). So, I finally resorted to grepping "fnmode" out of the sources, and found the location that sets this. Then, I noticed that the kernel module that handles Mac key mappings had a parameter that could be changed, called "fnmode". Well, that gave me a clue that it may be in /sys/ somehwere. So, I searched, and sure enough, it was there. The following command will set the function keys to be the default action, rather than media keys.
echo 2 > /sys/module/hid_apple/parameters/fnmode
The valid values are (0 = disabled,  = fkeyslast, 2 = fkeysfirst)
This effectively reverses the function key/media key mappings.
If you plan on buying memory, it most certainly MUST be Kingston memory. I bought 4G of Kingston memory from CDW Canada, for my Macbook, and it was DOA. I tried it in my Macbook; Linux was freezing up, and Mac OS X was telling me I had to restart my computer.
CDW doesn't do returns, so I called up Kingston. I told them the situation, about how I put the memory in my computer, and my computer quit working, but works with my other RAM. They immediately issued me an RMA number, and told me that they would be emailing me instructions on how to send it back through fedex; the fedex charges would be billed to them. I'm like "WHAT"???? You guys are paying the shipping charges? I was totally expecting to have to pay shipping myself. So, I proceeded to ask if they were paying shipping charges because I had just purchased it, or if this was the case for the life of the product. She told me that it was included with the lifetime warranty.
Now that is what I call a lifetime warranty. So, suffice it to say, I will only buy Kingston memory. KINGSTON ROCKS!!!
