If I expect their useful help for deeply system integrated tools like 
Oracle, or graphics device drivers, or even kernel related functionality 
like Wacom graphics tablets and the requisite kernel module, you're 
damned right I tell them. It's relevant, and I've in fact helped debug 
hardware related issues with all of those professionally.

Nonesense. I've *been* the vendor, and it makes a big difference what 
kernel you're using. Lying to them just confuses the issues, and I've 
run into *that*, too.
