But you can mix the two. Use a 64bit kernel (yes, sarge does have
those in i386) while keeping your 32bit userland.
That way you have all the stability of sarge i386 and the hardware
support for >4GB ram of amd64 without resorting to crude hacks like
PAE that cost cpu time.

PS: you will have to install iptales from amd64 if you need that to
keep working though.
