Since this series is also supported in the ata-intel driver ..
{ ATA_I82801GB, 0, 0, 1, ATA_UDMA5, "ICH7" },
{ ATA_I82801GB_S1, 0, 0, 0, ATA_SA300, "ICH7" },
{ ATA_I82801GB_R1, 0, 0, 0, ATA_SA300, "ICH7" },
{ ATA_I82801GB_AH, 0, INTEL_AHCI, 0, ATA_SA300, "ICH7" },
{ ATA_I82801GBM_S1, 0, 0, 0, ATA_SA150, "ICH7M" },
{ ATA_I82801GBM_R1, 0, 0, 0, ATA_SA150, "ICH7M" },
{ ATA_I82801GBM_AH, 0, INTEL_AHCI, 0, ATA_SA150, "ICH7M" },
.. and it seems that PCIR_BAR(5) is already set as I/O, you could try
adding the INTEL_AHCI attribute to the entry for "ATA_I82801GB_S1",
which matches your chip-id and see what happens.
I have not tried this - please make sure you have a full backup first!
