H A Dvmwgfx_msg.c35d86fb6 Mon Mar 20 21:09:48 CDT 2023 Zack Rusin <zackr@vmware.com> drm/vmwgfx: Print errors when running on broken/unsupported configs

virtualbox implemented an incomplete version of the svga device which
they decided to drop soon after the initial release. The device was
always broken in various ways and never supported by vmwgfx.

vmwgfx should refuse to load on those configurations but currently
drm has no way of reloading fbdev when the specific pci driver refuses
to load, which would leave users without a usable fb. Instead of
refusing to load print an error and disable a bunch of functionality
that virtualbox never implemented to at least get fb to work on their
setup.
