As someone (a broadcast engineer with 40+ years of carrying what used to
be a 1st phone) obviously more familiar with the FCC R&R than you
apparently are, Christoph, I'll have to argue that point. Intel has no
legal choice in the matter because the FCC had decreed that the stuff
to enforce the radiation limits either has to be in a custom made for
each country chip, or in binaries that check themselves for tampering
by secure crc, md5sum or similar methods. If the modules crc changes,
it must do an instant disable of the transmitter functions and exit or
crash, thereby precluding any 'hot rodding' of the chipset.

So basicly, you can accept it with the wrappers Intel provides, or linux
will not have access to the use of these devices, any of them that fit
in the category of "software radios". Intel et all has NO choice in
the matter in this country by FCC decree, and I believe its copycatted
by the Canadien DOC by treaty. Other locales may change the rules
slightly and often do, hence the requirement for manufacture of the
software radio, one thats totally controlled by the software issued for
that locale's use.

The fact that they are furnishing a wrapper, somewhat in the ndiswrapper
style, says that Intel would like a piece of this market, but with the
choice you are giving them with this arbitrary statement, they have no
choice but to quietly fold up their tents and go home. You are asking
Intel to break the laws designed to enforce the use of the 802-11 bands
in a legal manner.

So you might want to rethink your objections. I agree that it should
never become a piece of the kernel because it can't be audited, nor
even dissed without a DMCA prosecution, but we've been using nvidia's
stuff in modular fashion for quite some time, usually with decent
results. Its up to the user to install it of course, but thats
precisely the same scenario here with the Intel code. Intel will have
to put it someplace where the *user* can download it, meaning a server
setup someplace as opposed to handing the kernel developers one copy,
but thats the breaks as we've chosen to do it. Intel will also be
expected to supply a method of fileing bugs in case it doesn't work. A
publicly postable list that is actually supported for any and all bug
claims posted. Its an expense for intel of course but thats their
price of having a dog in this fight.

Cheers, Gene
