XP drivers for I/O?

I've been teaching a college level course on and off thru the years on x86
asm and arch. Last time I taught we had Win 98 and of course this OS
allowed anyone to access the PC I/O like serial ports, ISA bus, printer
ports,etc. Of course the new OSs like XP don't allow that. I've been
looking into writing a driver for an ISA proto board at the school, but it
appears Win driver development with the MS DDK is not a trivial task -
especially if you wanted to stay in assembly. Has anyone seen a hack ( a
driver in assembly) or other workaround for this problem? Don't get me
wrong, I agree with the need for drivers in the newer OSs, and I'm not
trying to open this up to a discussion about the need for drivers for
hardware access. But for teaching, a driver is a distraction. For now, I
believe we will just scrounge up some Win 95/98 boxes and run with it. But
eventually it would be nice to develop code and control I/O on the something
like Win2K or XP.

Thanks,

Dave
