For kernel patches, you need to be working in the base directory of the kernel sources. For your tree, that would be in /home/2.6.27/rc4-wl. That way the patches will apply with the effective command of 'patch -p1 < patch_file'. For kernel patches, I use quilt so that patches are easy to apply and remove.

The above hunk is correct.

This does not match step 7 of the specs. It was not changed recently, but the code did not match what was on the web site. No, I don't know why.

This hunk does not match the specs. In addition, I think there are too many right-hand curly braces for it to compile.
