I am still trying to get VGA output on an epia-M10000. I've tried many configurations and none actually work. Here's a part of the BIOS output log:

What is that unsupport int 0xff? That's the only unusual thing that I see. It boots all the way to a login prompt on the serial port but nothing shows up on the monitor. It feels like I'm almost there.
