One thing you can do, is wire wrap the VID pins for 2.05v, but then always run the voltage with a lower BIOS "user define" vcore. For example: my 2.0a P-4 was wire wrapped for 1.85v modified voltage, but I usually had it set at 1.7v or 1.75v. Set the BIOS voltage for "user define" at a reasonable voltage before doing the wire wrap. The only danger is if you ever have to clear the CMOS, the BIOS will revert back to all default settings and will think the 2.05v is default (because the wire wrap fools the BIOS). But, if you ever need to clear the CMOS, then you can always remove the VID pin wires first.
