I've compared the ini files for my Acer and a Fujitsu (Downloaded both 
drivers from the internet). As expected - there are some matching 
GUIDs, but also, quite a few are different (for example, the one 
labeled "CD volume"). It's a bit pity I couldn't find similarly 
distributed drivers for HP or Sony Vaio models (Along with Fujitsu, 
these are the only ones that are detected by the driver). Both HP and 
Sony distribute their drivers in exe format, and Sony requires you to 
enter your laptop serial number before giving you a link to the 
download. That sucks a little, as I'm not sure all that would install 
under Wine, or that it would have that ini file...

It would be great to get more ini files though. Or more information on 
them...
