This patch adds all the "tm_new" laptops information that is in acerhk 
to wistron_btns. That's about 25 more laptops. Obviously, I couldn't try 
them all. I've just tried the Aspire 3020. For this reason, I've also 
added a printk which ask the users of those laptops to confirm me it 
works (or not). Surprisingly, the dmi information could be found on 
google for a majority of the laptops, so it might not work so badly.

The information about which laptop has which led is also imported, 
however for now it doesn't do anything. It's just in case someone adds 
led support later, in order to avoid hunting information in the acerhk 
for a second time.
