SubjectTSCs are a no-no on i386
Hi!

This small patch fixes a long-standing problem for bare i386 CPUs. These
don't have TSCs and so, a recent 2.4.x kernel will simply halt the
machine leaving a text like "This CPU has no TSC feature (ie was
compiled for Pentium+) but I do depend on it".

Please apply. Worst to say, even Debian seems to start using i486+
features (ie. libstdc++5 is SIGILLed on Am386 because there's no
"lock" insn available)...

MfG, JBG
