I have not tried the proprietary driver, but AFAIK the blob does no attempts to put the device in D3 state.

I can try, but would it really help? Not all firmware have this loop and they will just assume that the link state is correct. This is the affected loop:

    While ((\_SB.PCI0.PEG0.LNKS < 0x07)) {
        Local0 = 0x20
        While (Local0) {
            If ((\_SB.PCI0.PEG0.LNKS < 0x07)) {
                Stall (0x64)
                Local0--
            } Else {
                Break
            }
        }

        If ((Local0 == Zero)) {
            \_SB.PCI0.PEG0.RTLK = One
            Stall (0x64)
        }
    }

In one trace I observed that the outer loop was executed 29 times which means that about 29 * (32 * 100us + 100us) = 95.7ms.
