Radeon HD 6xxx -> 6670 DSDT Patch

[Zackptg5]

I have the Sapphire Radeon HD 6670 1GB GDDR5.
Venid: 1002
Devid: 6758

HDMI and VGA both work (haven't tested DVI yet but it'll probably work too).
It works oob though I patched AGPM for my system def (iMac 13,2).

The problem is that in system profiler, it's listed as "AMD Radeon HD 6xxx"
I want to say 6670, not 6xxx

So I found what device it was under (PCI0->PEGP->GFX0) and added the following:

Device (GFX0)
{
Name (_ADR, Zero) // _ADR: Address
Name (_SUN, One) // _SUN: Slot User Number
Method (_DSM, 4, NotSerialized) // _DSM: Device-Specific Method
{
Store (Package (0x13)
{
"AAPL,slot-name",
"Slot-1",
"name",
"Sapphire Radeon HD 6670 1GB GDDR5",
"model",
Buffer (0x13)
{
"AMD Radeon HD 6670"
},

"device-id",
Buffer (0x04)
{
0x58, 0x67, 0x00, 0x00
},

"Display Controller",
"@0,connector-type",
Buffer (0x04)
{
0x00, 0x08, 0x00, 0x00
},

"@1,connector-type",
Buffer (0x04)
{
0x00, 0x08, 0x00, 0x00
},

"@2,connector-type",
Buffer (0x04)
{
0x00, 0x08, 0x00, 0x00
},

"@3,connector-type",
Buffer (0x04)
{
0x00, 0x08, 0x00, 0x00
},

"hda-gfx",
Buffer (0x0A)
{
"onboard-2"
}
}, Local0)
DTGP (Arg0, Arg1, Arg2, Arg3, RefOf (Local0))
Return (Local0)
}
}

No matter what I do though, it won't change anything. What am I doing wrong?

Bump. I've seen this question in many places yet no one has an answer for it.
