On an alix board with 256MB of RAM + 2G swap it is holding up OK. With low-spec machines like this you need to add lots of swap or you will need to get a bit creative. You can't use out of the box defaults on this machine in any case, so some tweaking is required anyway. For library relinking there's an rc.conf.local option to turn it off. You can disable automatic kernel relinking, there is one obvious line to remove from /etc/rc. You can still relink the kernel occasionally if you want the added security. Secret tip: You can compile an i386 kernel on a fast amd64 machine which will also "relink" the kernel of course, just go into sys/arch/i386 and do the usual kernel compile steps. Don't tell anyone I told you that! If you want to go further and have another faster i386 machine you can follow the release(8) man page to build custom release sets for your i386 laptop with all the tweaks it needs included.
