New nvidia drivers available

[Doug Rabson]

The latest 6113 build of the nvidia graphics drivers has just appeared 
on nvidia's web site. Check out 
http://www.nvidia.com/object/freebsd_1.0-6113.html if you are currently 
using the nvidia proprietary drivers. This driver works nicely on 
FreeBSD-current and while this version is not thread-safe, it does not 
conflict with libpthread or libthr's use of %gs so you don't have to 
map everything down to libc_r any more :-).

There will be a thread-safe driver available for FreeBSD-current 
sometime after I commit the pthread parts of the TLS support code.
