No, it can't be used from inside the graphics driver, as they both use the same memory.

Gábor Lénárt, I thank you for your interest in Hidden64.  It uses dedicated functions to access hidden RAM.  For example, the hidereadb() function first disables IRQs and the kernal/IO, reads a byte, then reenables IRQs and the kernal/IO.  Using Hidden64 requires editing your code, though.  I e-mailed UZ the beta, but I don't see it on the contrib site.
