does vmwgfx work at all?

[Yuri Pankov]

(resending as apparently the message didn't get through)

I am trying to use the vmwgfx module on VMware Workstation 15.5.1 VM, 
running 13.0-CURRENT, and it seems that none of drm-current-kmod and 
drm-devel-kmod's modules work -- former simply reboots the system 
(panic, unable to save dump), latter panics as well (below).

https://wiki.freebsd.org/Graphics lists vmwgfx as "experimental", but 
OTOH the wording there seems to suggest it should at least load.

Any hints?
