In step 2 wouldn't it be simpler to just replace all instances of 2922 with 2923? No other changes of the IAAHCI.INF file would be needed. Or, am I missing something? That would also eliminate any confusion when people can't find the line PCI\VEN_8086&DEV_2923&CC_0106.DeviceDesc = "Intel® 82801HR/HH/HO SATA AHCI Controller" because Intel has updated the drivers.
