This is a shining example of why people should avoid binary drivers. I'd
guess that the bug is related to the new 64-bit capability code.

It'd be really interesting to know what this driver is doing with
capabilities in the first place.

If anyone is using this driver, the output of the following command as a
non-root user from gnome-terminal or similar may be of interest:

$ cat /proc/self/status |grep ^Cap

It should generally be all zeroes.
