"This case is only for 'India'"
Yeah, only the second largest population in the world. :P
But you're right. They obviously have a table that would work much better on Linux, but it's only sent to Windows version now. Linux gets another table, full of bugs. So they are not stupid, they can write a (almost working) table. So why not send it to Linux as well? They are evil.
Anyway, I checked my Asus P5K3 Deluxe/Wifi-AP with Intel P35 / ICH9R chipset. It has the same DSDT code.
So what's interesting is how many boards this effects. This is something that we need to stand up against and make our voices heard.
Not only do they not support Linux, they go even further: they sabotage Linux.
