In NT4, MS decided to move the graphics subsystem into kernel mode
because it would 'improve graphical performance'. Why graphical
performance matters on a server is beyond me. [the fact that this
means you're more likely to crash the entire system is another matter,
suffice to say that IME, NT 3.51 was more stable]

Quite. The only people who will benefit by the GDI being moved into
the kernel are those who hammer the graphics. And they should be using
Win9x (for games) or SGI's Visual Workstations if they want _serious_
graphics on a PC.
