Although I agree that {ATK,TOS,FUJ,IBM}* give pretty much a certainty
these are OEM-specific, I think we'd need some evidence that
{ACCE,TBLT,IPML,FnBT}* are generic enough to grant them a non-classmate
driver.
What I mean is that we should push this driver forward and turn these
into a generic driver if we get some evidence these are not
Classmate-specific. And that will happen when we hit some other system
with these devices.
And what would be the consequences to this decision? Renaming the
driver, changing the config location and documentation. Splitting them.
I can't think of anything else. If splitting them would be interesting
by now, we can do it.
That's my opinion. Please, tell me what you think of it.
