Sorry for jumping in late.
The VMware Fusion Easy Install feature creates a Windows XP VM with the SCSI drivers installed. It stifles the warning by adding the following lines to the .vmx file inside the VM's directory:
lsilogic.noDriver = "FALSE"
buslogic.noDriver = "FALSE"
You can also add these lines manually to your .vmx file if you don't want to disable the hint for all VMs as etung suggested.
