Sure, we definitely need to do that, and more specifically:

1) we have to check first with how many different types of cpus are the
1810s being shipped and

2) whether the thermal settings of those cpus differ

because if they do, you need to check for cpu types also and not only
bios version and product info, which can get very hairy very fast.

And for all those thermal settings we need official documentation and
cannot accept any other sources.

That's why I keep questioning whether it makes sense for 1810 users (or
users of something else besides acer aspire netbooks with atom cpus, for
that matter) to use this driver.

What models are those, are those only aspire one netbooks or anything
else acer dumps out?

Bottom line is: I'm trying to understand what this driver should and
should not support? Frankly, I don't want to make it easy for users
to do fan control and break their hardware while doing so. Actually,
if acer's system builders would've done their job right in picking a
quieter fan for their packaging we wouldn't be talking here in the first
place. For example, I have also a lenovo edge and I almost can't hear
the fan there but that's a different story.

See what I'm sayin'?
