GIT is latest andy-tracking head (happens with any version up to head)
and the config is basically as I posted it a few days ago for my Ar6k
problem (which works now) except for the removal of the VT console
support. The same functionality is reached with the attached patch and
setting the new option to "n" (BTW: I would also like to see this patch
go upstream ;)
The same patch/modification works without problems on GTA01 so I would
suspect something around glamo, but there might be other nitty gritty
details involved...
