I was able to load the qutopia linux thing. I thought this would be easy.
The instructions are a little to vague. Not everyone has compiling experience In your instructions you say Download usbtool from SVN and read the README. Well you also have to download some other files from there and you do not mention that. Can you check your zip file and make sure you did not leave out the rockbox.bin see attached picture. Screen shot of the zip file opened. Please have a look!

Oh, sorry; I meant rockbox.vx747 instead of rockbox.bin :-[
You'll need the bootloader, as rockbox.bin doesn't come with rockbox.zip
I know the instructions aren't that good, I'll need to rewrite it a bit but the whole 'upload firmware to the device' process isn't finished actually (just as this port).
I'm currently more focused on getting Rockbox to work on the device than getting other users be able to replicate my case..

I had some success on my Onda 777.
I returned the retval in the "mmc_select_card()" function earlier to see where the error (ATA Error: 11) occurred and then suddenly Rockbox boots up fine.
if (sd2_0)
{
retval = mmc_read_switch(&request);
if (!retval)
{
mmc_switch_hs(&request);
jz_mmc_set_clock(1, SD_CLOCK_HIGH);
}
return retval; // <--
}
It's in the "ata-sd-jz4740.c" file.
After booting Rockbox the touchscreen doesn't work. With an older revision it worked but only 1 out of 10 times.
Do I have to press a button to activate it?

Are you sure you aren't just in the 3x3 grid mode? (vs absolute point mode?)
And no, there's no need to press a button to activate it.. Perhaps this is a calibration problem?
I'll look into it (and ata-sd-jz4740.c) later.

How can I find out if I'am in absolute point mode?
The times it works its in 3x3 grid mode.

Some people seem to have gotten Linux booting on these players: http://code.google.com/p/jz-hacking/wiki/Index?tm=6
