I have and I had the same in FreeBSD 7.0/7.1 and now with 8.0-CUR with
both a NV8600GTS and an older NV6800GT. A very old NV6600 never showed
up these lockings when I used that PCIe-Card with FreeBSD 7.0/7.1, but
I'm not sure. The locks came spontanous, sometimes after heavy usage of
'mplayer', but sometimes instantanously after the destop showed up.

On those boxes, there is no Linux emulation and no Linux BLOB (useless,
due to 64 Bit). I swapped the 'nv' driver on all FreeBSD boxes with
'vesa', because there is another issue with sprites/graphics buffers
many times reported using FireFox.

When the display got locked, sometimes I had the chance opening a ssh
session killing Xorg/xdm and restarting working, but by the end, that
was when changing towards 8.0-CUR, this 'trick' didn't work anymore. On
FBSD 7, Xorg was eating up 100% CPU time.
