Okay, I was announcing a QUESTION. Do you think it makes sense
to simulate the TSC from DOS, even for DPMI ? We could for example
return 1000000 * timer ticks (the common 40:[6c] value...) or even
some more stupid value. Would that make sense??? Do you know of other
"TSC-less CPU helpers"?

I personally think that programs SHOULD first check for the existance
of the TSC before using it, but, well... some programs just fail to be
sane.

Well, personally, I believe that if the programmer is dumb enough not to read the docs and perform the checks described in there, said programmer deserves it if his code fails... but, that's just my personal opinion ;-).
