How to make GPU BIOS accessible?

[BoggledBeagle]

I think it would be useful to be able to set power limits (or other things) directly in the GPU BIOS. For example, if somebedy for whatever reason does not want to use the whole power envelope of the card, he should be able to enter the BIOS and lower the power limit.

Why is not the BIOS of the graphic card accessible and configurable?

Are there any tools available to enter the GPU BIOS and change some settings?

The cards may have some multi position switch on them to tweak the power limit, with for example 0, -10, -20, -30% selection.
