[Michael Butler]

SVN r226302 solves the ichwd failure to attach issue .. instead of ..

isa_probe_children: disabling PnP devices
ichwd0: <Intel ICH7M watchdog timer> on isa0
isab0: found ICH7 or equivalent chipset: Intel ICH7M watchdog timer
pcib0: allocated type 4 (0x1030-0x1037) for rid 0 of ichwd0
pcib0: allocated type 4 (0x1060-0x107f) for rid 1 of ichwd0
ichwd0: unable to reserve GCS registers
device_attach: ichwd0 attach returned 6

  .. I now get ..

isa_probe_children: disabling PnP devices
ichwd0: <Intel ICH7M watchdog timer> on isa0
isab0: found ICH7 or equivalent chipset: Intel ICH7M watchdog timer
pcib0: allocated type 4 (0x1030-0x1037) for rid 0 of ichwd0
pcib0: allocated type 4 (0x1060-0x107f) for rid 1 of ichwd0
