    I can't disclose them, but I've obtained some source code for a 2.35.7 kernel image which is compatible with our tablets (with mine at least).

    I have obtained then from a manufacturer which is called Smallart.

    As you know different hw version of the Renesas tablet exist, though extremely similar. Smallart could provide a patched version of the kernel source which works for the "Liveall" ones, which is the manufacturer of the tablet I own. I'm not even sure if Smallart still sell their Renesas stuff right now. It may well be an aborted project for them (they say they met "lots of problems").

    A third manufacturer is called "Topwise". See some references below, to compare pictures and understand which one may be yours:

    I can't make Smallart kernel sources public (yet...) but I can succesfully recompile and make it work on my tablet, so I think this is a good starting point. That's why I wanted to share with you.

    I also think replacing the kernel and not the Android fs is bringing some incompatibilties. I can share the entire Smallart firmware package, if you wish. Once more, this is for testing only, but I fixed something at least:

    - 3G power can't be controlled by Android settings, but at least I made it to switch off when WiFi is on and viceversa (applies only to version with internal 3G).
    - G-Sensor now working.

    An issue I'm aware about is that, randomly, using the touch keys sometimes make the system hang. The I2C bus is involved, returing an error, but I'm not able to find the actual root cause. If anyone could help here, I can share some additional info (PM, only if you think you can help with coding - thanks).
