I only found two interesting pieces of information

It just occurred to me where I had seen this type of black screen problem
before. It happens when using the "vesa" driver with an 845G. We work
around this in the i810 driver by remembering the initial video mode
and simply re-initialising it when exiting/VT switching instead of using
the VBE save/restore mechanism. This workaround is only actived for
845G hardware.

There was no answer to this posting, neither about success nor failure
with this change.
