Dusted off a tablet this weekend and tried out one of the newer puppy like distros out there called MacPup. Its basically Puppy Linux but with the E17 window manager. Since it lines up with Ubuntu releases it was easy to get a touchscreen working. Otherwise the hardest part of crafting linux for these tablets.
Anyways here is a link:
This was built on LX800 hardware and with the smaller of the two internal flash drives. As this is puppy I would think that it would work on GX series as well but I am not sure. This is a .img file so dd is your friend. This also means that unetbootin or any of the standard usb boot manipulators will not work. If popularity demands it I will make a clonezilla installable backup. Until then dd away and let me know if anyone has any problems. Hard buttons work and so does suspend.
