AFAIK, no. The 4.4-RELEASE CD states 16MB - most of this is because the installation filesystem is an MFS unpacked off the floppy. Once you've installed the system, it'll run in 8MB. Your options would seem to be: 1) Temporarily find more memory. 2) Move the disk to another system, install it there and move it back. If you're feeling adventurous and not planning on changing your current partition sizes: 3) Unpack the installation MFS into your swap partition and boot into that, then install as normal. 4) The installworld process only uses a couple of dozen files from the existing userland to manage the install. If you copy a -STABLE /boot hierarchy, the files needed to start NFS (ifconfig, nfsiod, mount_nfs) and the files needed for installworld (see the installworld target in /usr/src/Makefile.inc1), you should be able to boot single-user, start the network, mount your build server and do an installworkd. For either of the latter two options, you'll need to manually update your bootblocks to a 4.x version before rebooting.

I'm not so sure. In Feb 2000, I did some tests using 3.4-STABLE on a Pentium-133 and found that it could manage ~20Mbps (probably full size packets) with natd and IPFW (natd being the big killer). If you didn't need natd, I'd be confident but I think you might have problems trying to get 1.5Mbps though natd on a 386. You might like to look at IPfilter instead - it does NAT in the kernel and should be much faster.
