I am experiencing a similar problem since updating my system this
morning (started a seperate thread, but somebody was kind enough to
point me to this one). In my case the problem is with regards to
on-board nVidia nForce MCP55 SATA300 Controllers.

The missing devices in my case are:

ad4: 238475MB <SAMSUNG SP2504C VT100-50> at ata2-master SATA300
ad6: 476940MB <SAMSUNG HD501LJ CR100-10> at ata3-master SATA300


acpidump -t shows the following MCFG table:
/*
  MCFG: Length=60, Revision=1, Checksum=108,
        OEMID=090607, OEM Table ID=OEMMCFG, OEM Revision=0x20070906,
        Creator ID=MSFT, Creator Revision=0x97

        Base Address= 0x00000000e0000000
        Segment Group= 0x0000
        Start Bus= 0
        End Bus= 255
 */

devinfo -r output:
