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.
