I was under the impression that there is no autodetection in the case
of shared video ram. In any case, using a different VideoRam setting
or none at all does not change the problem.

Googling for the Xorg error message gave a few hits, e.g.

https://launchpad.net/distros/ubuntu/+source/xserver-xorg-video-i810/+bug/22741

which makes me think this is not a FreeBSD-specific problem. Moreover,
it is likely to get fixed in a new release.

So what I'd like to focus on is how I can get my console back after X
got stuck.

I tried both ways you suggested:

1) run startx blindly. The login test told me that the box still
listens to keypresses, so I assumed this might work

2) log in via ssh and run startx </dev/ttyv0 

I assume that the duplicate "Error in I830WaitLpRing" entry in
Xorg.0.log is all I get. As I told previously, the screen is still in
graphics mode, so whatever shows up on stdout or stderr is lost on me.

I tried the vidcontrol stuff without X. Setting 80x25 or VGA_80x25
does work, whereas VESA_132x25 causes an error message saying VESA is
not supported.

However, if I try one of these suggestions after X froze (either
blindly or through ssh) the screen is not affected except that it
sometime goes from all white to all black.
