    I sent verbose lspci and acpidump via private email. Regular lspci
    looks like: (booted in dock but now undocked, sorry).

    The ffff: lines are probably what is contained inside the dock.

    Device GDCK looks like dock to my untrained eye. Unfortunately its
    type is IBM0079... ...

    Ahha, and ibm_acpi.c agrees with me.

    IBM_HANDLE(dock, root, "\\_SB.GDCK", /* X30, X31, X40 */

    Scope (\_SB)
    Device (GDCK)
    Name (_HID, EisaId ("IBM0079"))
    Name (_CID, 0x150CD041)
    Method (_STA, 0, NotSerialized)
    Method (_DCK, 1, NotSerialized)
    Store (0x00, Local0)
    If (LEqual (GGID (), 0x03))
    Store (\_SB.PCI0.LPC.EC.SDCK (Arg0), Local0)

    If (LEqual (GGID (), 0x00))
    Store (\_SB.PCI0.PCI1.DOCK.DDCK (Arg0), Local0)

    Return (Local0)

    Method (_EJ0, 1, NotSerialized)
    If (LEqual (GGID (), 0x03))
    \_SB.PCI0.LPC.EC.SEJ0 (Arg0)

    If (LEqual (GGID (), 0x00))
    \_SB.PCI0.PCI1.DOCK.DEJ0 (Arg0)

    Hope this helps.
    Thanks, Sharp!
