It comes down to personal preference I guess.  To me, having a single
relatively non-changing file in /etc that gives the same behavour
regardless of what kernel I'm booting seems like less maintenance :-)

That said, I don't think there's a kernel option to do what you want -
you'd probably need to play with tc_quality value in arch/x86/x86/tsc.c
to bump it higher than than whatever is the default timecounter.  And
that's even more maintenance again...

It would also be nice to work out what the underlying problem is.  What
is the output of "sysctl kern.timecounter" on your system (before you
override kern.timecounter.hardware)?
