Actually the issue is caused by the Synaptics touchpad driver binding
to the PS/2 mouse device in qemu.
I have no idea how PS/2 devices are detected but the one present in
qemu is misdetected as a synaptics touchapd by the Synaptics driver
As a workaround I have patched my qemu to not enable the PS/2 mouse device.
