Thanks a lot for your support.
FYI, I finally got a picture ! All I needed to do was to use the magic
"security=none". But of course, it's not very satisfying ; it should work
without that. Please let me know if it works better with the new kernel
patches.
About the wayland-egl error message ("libEGL warning: wayland-egl: could
not open /dev/dri/card0 (Permission denied)"), I think I understood what
happens :
- libwayland-egl is used by all wayland clients
- libwayland-egl need to open /dev/dri/card0
- the wayland clients are run as user 'app'
- /dev/dri/card0 is owned by group 'video'
- user 'app' is not a member of group 'video' => denied access
As a test, I tried to add the user "app" to group "video" (with "usermod -a
-G video app"), but got a "PAM authentication failure". I don't know how to
overcome this without recompiling the file system.

I've looked at the kernel used by the "Tizen on Yocto" today and found
that it lacks quite a few patches that went into "Tizen IVI", in
particular for the graphics drivers. I'm not sure whether these are
relevant differences, but will test it once a build with a refreshed
kernel recipe is done.
Regarding the previous releases: I don't know whether any image really
ever was tried on the VTC1010.
