you can set CONFIG_DEBUG_ADA_CODE to enable verbose messages in
libgfxinit. At least this would show if the GFX hardware is indeed
enabled or if it bails out for some reason.

When you set drm.debug=6 in your kernel command line, there'll also
be a lot of information in the log about what configuration Linux
finds before (re)initializing graphics.

Hope that helps,
Nico
