3.8.24 is also really old already, try going to 4.1 or 4.3 right away,
and submit any patches that you might need for integration into
mainline Linux once you are done.

See http://git.openwrt.org/?p=openwrt.git;a=tree;f=target/linux/gemini;h=b74c3d8f0100e2ac8a4d71c4d23c082db2993e63;hb=HEAD

for a tree that has some of the missing parts for gemini, including a
config and some drivers that might be helpful. This is based on 4.1
and should be easy enough to forward-port to 4.3 if you want.

Start with the config-4.1 file from openwrt.
