Don't you directly make bzImage or something similar ?

Reading the code, CS segment overrides aren't supported, though
data seg overrides are. I guess this is it.

I compiled my current kernel (2.2.10) with the default Makefile,
and Valgrind works fine. Another machine with 2.4.13 was compiled
with Pentium 2 opts IIRC, and Valgrind works fine too. Maybe the
culprit is the particular kernel you use, which happens to use CS
overrides ?
