Yes, that is what came to my mind too. So, ideally for a FreeBSD 5.x kernel it
should show gnukfreebsd5 and for a FreeBSD 6.x kernel it should show
gnukfreebsd6.
But on my system, where uname -a reports 5.4-1-486, the output from sys.platform
is gnukfreebsd6.
Which means the sys.platform output is being taken from somewhere else.

There might be a good reason behind that. Even for Linux systems the output of
sys.platform is linux2. I think sys.platform is caring only about the major
releases (though in linux major releases are 2.X)
And even if that's the (correct) case, sys.platform should output gnukfreebsd5
for a 5.x FreeBSD kernel installed.

Yes, that'd be my last option. But for the point I mentioned above, I think
there is a bug somewhere. Not sure if it's in the python package or any of the
freebsd related packages.
I also verified the installed FreeBSD kernel on my system and it says is
kfreebsd-image-5.4-1-486 5.4-21. I don't see any FreeBSD 6.x series kernel
image or utility installed on my box.
