I tried this out, but it is not working. Something breaks in the event
handling and event reference counting. Unfortunately my vacation is
pressing on, and I am not sure if I have time to debug the issue further
before that.

Anyway, I have attached the boot log with the following WARN dumps:
----------------------------------------------------------------

----------------------------------------------------------------

The first two came at boot time when setting up the fbconsole, the ones
after that came when I tried to use kmstest[1]. The fbconsole came up,
but nothing after that works.

I am back from vacation in the beginning of august, so there may be some
time before I can debug this further.

Best regards,
Jyri
