With 4 megs of ram, you'll likely be brought to your knees, particularly
since you're not using swap.  Forget about running X.  Before I got
16M ram, I ran with 8 and that was torture.  Sure, you've stripped your 
system down by removing drivers from getting loaded at bootup, but your 
system still needs to function.  To my recollection (on an OLD Linux
system without swap), you *can* run consoles (but rough) without swap,
but you'll barely be able to get out of the starting gate with X.  With
4m, you'd be lucky if the intro screen loaded. :)

If I'm correct, you don't have to make a swap partition but can
use /tmp (for example) as your swap space.  I think this is in the
handbook, where certain things are outlined to do this (including the
lines that go into /etc/fstab).  Once again, you'll have to read the
docs.

Well, I know your note contained a whole lot more, BUT it would probably
be best if you looked at http://www.freebsd.org and read substantial
portions of the handbook and mailing list documentation to get exactly
what you want (or put you into the right direction for a good solution).
