This is not my experience. Driver developers don't use oscilloscopes. Changing HW once the first prototype is done is expensive and it takes a lot of time for you to get the second iteration. Or you flip a bit in the driver to disable the new broken feature. Most of the driver development happens before the physical hardware even exists. Everything is virtual.

My experience is with firmware for embedded and consumer electronics, maybe video cards are sufficiently complex that none of the things I saw are even possible! Lots of issues resolving power states, clock trees, monitoring buses, docs from suppliers were always subtly wrong, power management chips never quite worked how they were supposed to, things like that.
