This is why "the other OS" has the WHQL, signs drivers and generally
does many things (including getting some cash from driver vendors) to
ensure (and enforce!) that the "designed for Windows xxx" logo really
helps customers.
And might be one of the reasons why they're releasing a new 'kernel'
version only once every two years and go through many pains to ensure,
that old drivers still run most of the times. This is an area where
Linux (and many of the Linux advocates) could really learn.
>From a user land perspective, only major Linux vendors or
organizations could enforce such a logo program, it would cost wads of
cash and it will really suck if you currently run the certification
process for Linux 2.5.102 for your driver and right before you're
done, 2.5.103 is released and you have to start all over again.
That's why most of the companies that _do_ provide drivers, provide
them for _one_ kernel release of some Linux distributions.
Heck, I was working with an IDS (won't tell you which one), which
shipped its security relevant kernel module _only_ for a truly well
known distribution with the stock kernel release which had remotely
exploitable holes.
While nVidia bashing is very popular on this list, this is one of the
few companies that, while distributing binary only drivers, try to
make an effort to keep their drivers reasonably up to date _and_ work
with most new kernel releases.
