Actually, the nvnet driver is not present in the Linux "ForceWare"
drivers for their mainboards. The reverse-entgineered forcedeth driver
is much more efficient than that of Nvidia (which had to be built from
source, by the way) consumes far less CPU and (in my case, anyway)
reaches higher transfer rates. First hand experience with an nForce2
motherboard, revealed that I could reach full 100Mbps (and virtual no
CPU usage) when transferring stuff to my file server where as I was
able to go as high as 55-60Mbps with the nvnet driver (and over 30%
CPU usage), so yeah, I'm 100% confident that the OpenSource drivers
here at least are 200% better than the proprietary ones, to the point
that the nvnet driver no longer is part of the "ForceWare", which is
actually excellent!

However for the video drivers, as was said in another post to this
thread by Rob, nVidia and ATi are not releasing specs for their
hardware for Open Source drivers due to incarnate battle over
features, price and performance... I would have to assume that an Open
Source driver initiative on at least the kernel end would be
tremendously helpful to prevent lockups and ease debugging, not to
mention that installing their binary X drivers would be much easier,
after all the kernel module pretty much is only a bridge between the X
driver and the hardware, the magic is done in the X driver, not the
kernel gateway (or am I terribly wrong here?)

Alas, I think that if either of the giant companies did fully open
their drivers and specs, not only would they be doing the right
thing?, but I believe it would be much easier to implement new
capabilities to the cards.
