Bug#982353: contrib/testing64 crashes on Vbox 6.1 when updated to kernel 5.10 due to deprecated use of graphic card

["Francesco P. Lovergine" <frankie@debian.org>]

Package: cloud.debian.org
Severity: normal

In order to replicate the issue, just up with a current image (20200607.1).  
Runnig the VM causes a kernel panic, as in the attached screenshot
Moving from VboxSVGA to VboxMSVGA solves the issue. That happens only after 
upgrading to current bullseye 5.10 kernel, instead of the historical 5.6.
Virtualbox in use is 6.1.18.
