Not sure if what comes with fedora is built for armv7 or notbut they do have 3 kernels respectively for sin5i sun5i and sun7i. I'll checkout as soon as I get to use my XZPAD700 again and I'll have an answer for the sun5i core.

Supporting Allwinner SOC would really probabbly require a 3.0 or a 3.4 kernel from the linux-sunxi branch (https://github.com/linux-sunxi/linux-sunxi) as many patches have not made it to kernel.org, or searching around for the patches to apply to vanilla kernel (that will will be probabbly conceived for ither a 3.0 or a 3.4 kernel anyway). But if you come up with something to test I can see if it works on my XZPAD700.
