Yes, fully agreed!

Please then me add the MSI U110/U115 support in msi-laptop driver. I am
sure the acpi baclight method works fine on U110/U115 and I hope the
_REAL_ opensource kernel user will not have a invalid backlight control
function.

For the native psb driver, if have anyone want to ship it with newest
msi-laptop driver, then he must need take care anything in KMP, like:
disable msi-laptop or put it to modprobe blacklist.
Because the native psb driver doesn't not included in kernel mainline.

On the other hand, the Poulsbo already stop to chip, there will not have
many machine ship the native psb driver with newest msi-laptop.


Thank's a lot!
Joey Lee
