I just looked at clock.s from djlsr110.zip in libsrc/c/s and I don't 
recognize any differences to earlier versions.

The important statement seems to be:

	.globl _clock
_clock:
	movl	0xe000046c,%eax

etc.

I don't see how this should work with DPMI. My limited assembler knowledge
suggests that there still is an absolute access to the remapped 1 Mbyte memory
area.
