This type of problem is difficult to debug. Once you are out of multiboot, the next code that touches the graphics adapter is the vgatext driver. You can look at vgatext_attach(), in particular vgatext_init(), to see if that's where things go wrong.
It's possible that some other hardware errors messing up video display as a side effect. On one system, probing an empty pci express bridge messes up the the display. I've also seen BIOS incorrectly accounting for shadow memory, resulting in shadow memory being used as normal ram. Video display is messed up when the shadow memory is being stepped on. I'd suggest you send the console to serial port and see if you can get the machine up. You can then debug the video display from the serial console.
