It is not clear what is going on. The object [^^^PEG0.PEGP.DD02] does in fact
appear in one of the SSDTs, and the _Q17 method executes properly here:

Executing with AcpiExec:

> acpiexec dsdt.dat ssdt6.dat

- find DD02
       \_SB_.PCI0.PEG0.PEGP.DD02 Device       00504430 04
            \_SB_.PCI0.GFX0.DD02 Device       004D17E0 01

- find _Q17
       \_SB_.PCI0.LPCB.EC__._Q17 Method       004C0420 01 Args 0 Len 002E Aml
00492187

- eval \_SB_.PCI0.LPCB.EC__._Q17

[AcpiExec] Global:    Received a Device Notify on [DD02] 00504430 Value 0x87

0x2 Outstanding allocations after evaluation of \_SB_.PCI0.LPCB.EC__._Q17
No object was returned from evaluation of \_SB_.PCI0.LPCB.EC__._Q17

This is with ACPICA version 20120913. We may have to attempt to reproduce the
problem with version 20120320.
