Is it a NIC that is supported?

Well, I would guess that they probably "turn off" this stuff by omitting
the code necessary to do it for the most part. That way the download is
smaller, and to "turn on" these features again would require basically
reimplementing them.
Then again, I'm no expert. I don't know how exactly they did it. (It's
something like a 100 MB download.)

Oh yeah, you gotta give them a whole load of personal data. Plus the
installer scans your PC and generates a hash code based on your
hardware, and you have to send this code to get the license key. So
they're determined that you should only install this program on *one*
PC. (Which seems somewhat counter-productive to me... I mean, it's not
like they gain anything by making it harder to install on several PCs.)

Heh. Not "what you offer" but rather "what they demand". ;-)

Define "supported".
It tends not to be a problem these days. But for example, when I first
set up my shiny new socket-939 board with the brand new nForce-4
chipset, none of the distros I tried could handle the SATA controller or
either of the two NICs.

Perhaps; some eval software (which this *could* be seen as) has stuff
just "turned off", while others have elements ripped out. Ripping out
bits, though, requires more work and regression test - especially for
gratis software, since you don't want to leave the prospective customer
with a bad impression.

It's always hard to know for sure unless you have access to the code,
that's for certain.

If that's the case, then they've done a fair amount to identify the value
of that to them.

Well, no, you "offer" it in exchange for the goods or services. If you
don't offer it, then you don't get the goods or services.

One that a driver is provided for and that has been verified to work.

I've got a system with an nForce chipset, but I'm not sure which; newer
hardware sometimes isn't supported right away when the specs change and
aren't shared with the kernel devs, though; the wireless card in this
machine (it's the one I'm using, actually) doesn't work well with Linux,
but it's not important to me because the system is right under my
ethernet switch and has a functioning ethernet card in it.
The wireless *works*, but after a few minutes of serving up data, it
starts doing something (not sure what, haven't diagnosed it) that kills
my access point completely.
But when I first installed Linux on it, the card wasn't even recognized
because it was so new.
So it has improved.

My dad keeps complaining that ever since he upgraded to a new version of
SUSE, his network access has slowed to a crawl. Eventually he reverted
to the old version, and it speeded up again. Go figure...

He might ask a question on forums.opensuse.org and provide some details.
It's possible he needs to disable ipv6 both in the kernel and in Firefox
- a simple fix to improve performance.

GOOGLE!
1) I wanted to learn about the views of a professor with an Asian name. I was
hopelessly thwarted because Google insisted on giving me hits with tons of
variations of spellings-- despite use of "" and +.
2) I did an image search on Google of someone I thought I knew from college,
first name Lynda. Of course it had to show me an image of Lynda Carter.

I'm guessing you spelled it wrong. Like, with latin characters or something. ;-)
