My house nameserver is a 96M NetBSD/sparc machine, running BIND. I'm
not running huge zones like .com, but there is one that's not entirely
trivial (somewhat over two thousand records). According to top, it has
64M RAM free, and that's without even touching swap, so I'm fairly sure
96M is substantial overkill for the application.
Of course, the plural of `anecdote' is not `data'. But I do believe
that you don't need anywhere near a quarter-gig of RAM just for an OS
and BIND unless the OS is pretty severely bloated or you're serving big
zones.
Now now, this is classiccmp, you know how we hate real world
experience here.
My DNS server currently handles 319 zones, and functions as a resolver
for about thirty machines. Running BIND9 on an UltraSPARC-IIe at 500MHz
(Netra V100) with 1GB of RAM running NetBSD/sparc64 v5. No graphics or
other foolishness on this server-in-a-rack machine. It is also a build
server for a couple of software projects; when those jobs kick off it
gets a bit swappy, but it's fine otherwise.

A modern Linux or BSD distribution [...] but I've
found most will
run well with 128MB so long as swap is available (and you aren't
running BIND).
I've got machines with 256 MB of RAM running current Debian
Linux
just fine. And yes, one of them is actually running BIND. For
rather small zones, admittedly.
