Yes, looks like the bug it trigger during a vesa resolution change. I
have try to use the vgabios blob that we use for qemu-traditionnal and
it works fine. But with the vgabios blob provided by qemu, it does not
work... I'm still not sure of what the bug is, but I'm getting closer to
it.
Also, this happen only on an Intel machine, on an AMD machine,
everything works like a charm.

More detail, if anyone want to know:
It's look like syslinux is doing a int 10h call that never return to set
video mode:
Int 0x10, with AX=0x4F02
