SEGV with games/linux-ut

[Sean C. Farley]

Alexander and I are getting SEGV's when trying to run games/linux-ut.
He also sees problems with Serious Sam.  It does not occur for him with
an FC4 base.

Criteria for SEGV:
1. linux_base-f8-8_{4,6}
2. compat.linux.osrelease: 2.6.16
3. RELENG_7 (r183556) with or without patches for Flash 9 support
4. nvidia-driver-173.14.12
