Bug#976807: debian-installer: Bullseye d-i Alpha3: qemu ramfb and virtio-gpu are unusable for graphical installation

[Ryutaroh Matsumoto <ryutaroh@ict.e.titech.ac.jp>]

Package: debian-installer
Version: 20201202
Severity: normal

Dear Maintainer,

I tried to use Debian Bullseye arm64 d-i Alpha 3 to install Bullseye
to a QEMU disk. I tried -device ramfb and -device virtio-gpu-pic
for graphical installation by d-i Alpha 3. But neither of them were
used by the Alpha 3 installer and text-based installation begun.
The full commands for starting qemu-system-aarch64 is as follows.
Host Debian Linux is ARM64 Bullseye, so I used -enable-kvm.

Note that ramfb and virtio-gpu-pci are only choises for qemu-system-aarch64, as
