Hi all,
I have made some progress in my flat panel work, but I run into a very interesting problem. It looks like that int10 is not handled by VBios but by SeaBios itself.
The SeaBIOS int10 handler is overwritten by the vgabios. So, for some reason the vgabios didn't install a handler. The log excerpt you included doesn't go far enough back to see what happenend during the vgabios execution. Make sure you are running the vgabios from SeaBIOS (not coreboot) and add debugging to it to verify where it is failing.
thanks for the hint... I let coreboot load the option rom to 0xc0000 but let it not start and in SeaBios I am using CONFIG_OPTIONROMS_DEPLOYED to start the loaded VBios. But there is lot to do before the bootsplash gets shown :(
SeaBIOS needs to be the sole executor of option roms. Things tend to mysteriously break in any other configuration.

The bad thing is that it does not display my bootsplash correctly but the good thing is that it shows everytime (warm and cold reboot) the same "image" :) And text modus ist not working right now...
