Just an update: there is a new nvidia-drivers-295.49 in portage, with
this I no longer have an X segfault but the screen is blank and keyboard
is dead (Num Lock not responsive, CTR-ALT-F1 or CTRL-ALT-Backspace have
no effect). I can ssh into the box and X seems running happily, no
errors in the xorg.log but no video. The syslog contains some "Xid"
lines which according to the nvidia README indicate that a general GPU
error occurred:
