I'm still unable to change the screen backlight intensity.
The headphones plug works properly when loading snd-hda-intel with model=laptop option.

I *think* I fixed this one by doing this:
Device (PMIO)
{
//(...)
Method (_CRS, 0, NotSerialized)
{
//(...)
Name (IORT, ResourceTemplate ()
{
IO (Decode16,
0x0000, // Range Minimum
0x0000, // Range Maximum
0x01, // Alignment
0x80, // Length
_Y02)
//(...)
IO (Decode16,
0x0000, // Range Minimum
0x0000, // Range Maximum
0x01, // Alignment
0x80, // Length
_Y07)
IO (Decode16,
0x0000, // Range Minimum
0x0000, // Range Maximum
0x01, // Alignment
0x40, // Length
- )
+ _Y09)
//(...)
CreateWordField (IORT, \_SB.PCI0.LPC0.PMIO._CRS._Y02._MIN, I1MN)
CreateWordField (IORT, \_SB.PCI0.LPC0.PMIO._CRS._Y02._MAX, I1MX)
//(...)
CreateWordField (IORT, \_SB.PCI0.LPC0.PMIO._CRS._Y07._MIN, I6MN)
CreateWordField (IORT, \_SB.PCI0.LPC0.PMIO._CRS._Y07._MAX, I6MX)
- CreateWordField (IORT, 0x42, I9MN)
- CreateWordField (IORT, 0x44, I9MX)
+ CreateWordField (IORT, \_SB.PCI0.LPC0.PMIO._CRS._Y09._MIN, I9MN)
+ CreateWordField (IORT, \_SB.PCI0.LPC0.PMIO._CRS._Y09._MAX, I9MX)
I'm not sure about this.. I have only imitated previous statements :D
Although, after fixing a few more common compile errors and compiling the dsdt, the kernel
boots without acpi errors and it even detects more devices.
Here is the difference:
Before:

ACPI Error (uteval-0236): Method execution failed [\_SB_.PCI0.LPC0.PMIO._CRS] (Node ffff81007ff1cc70), AE_AML_BUFFER_LIMIT

Don't know what this new device is.. Also I didn't notice any change
on laptop behaviour.
