Hi /prog/

would it theoritcally be possible for an OS to make use of the RAM on a graphics card as system RAM, eg at boot?

The problem is generally that it takes less code to initialize the DRAM controller on a motherboard (or inside the CPU, as it often is the case in newer computers) than it takes to (1) initialize PCI (2) find the graphics card (3) tell the graphics card to map its RAM at a given physaddr.
