Matt Zimmerman reported a regression using NV11 card from 6.8.2 in 7.0.0 using
only the TV output.

See: https://launchpad.net/distros/ubuntu/+source/xserver-xorg-driver-nv/+bug/41934/
for card details.

The regression has been introduced with this commit:
https://bugs.freedesktop.org/show_bug.cgi?id=3095
https://bugs.freedesktop.org/attachment.cgi?id=2501

The new code introduced in nv_setup.c causes the full hang of the machine.

This workaround seems to fix the problem but of course i am more interested to
know if this is the right fix or not.

Thanks
Fabio
