The original GENERATE patch that I sent to ISC would generate A records.
But I'm sure there was something I overlooked, since this was changed in
the version that was included in 8.2.1.
Excerpt from the patch below.

I believe I now have a suitable patch for 8.1.2-T3A which implements
Mark Andrews' suggested syntax. Note that in this implementation the
iterator is allowed to appear *within* a string, not just at the
beginning. So you can do
$ORIGIN 10.36.158.in-addr.arpa.
$GENERATE 1-31 * CNAME *.0.10.36.158.in-addr.arpa.
to generate
1.10.36.158.in-addr.arpa. CNAME 1.0.10.36.158.in-addr.arpa.
..
31.10.36.158.in-addr.arpa. CNAME 31.0.10.36.158.in-addr.arpa.
and for instance
$ORIGIN uninett.no.
$GENERATE 1-255 pc*.uninett.no. A 158.38.60.*
to generate a bunch of anonymous names for PCs.
...
+ /* We only handle CNAME, PTR and A so far */
+ sprintf(data, gen_buf, i);
+ switch (type) {
+ case ns_t_cname:
+ context = domain_ctx;
+ break;
+ case ns_t_ptr:
+ context = ns_ptrcontext(domain);
+ break;
+ case ns_t_a:
+ context = domain_ctx;
+ if (!inet_aton(data, &ina))
+ ERRTO("$GENERATE IP address");
+ (void) ina_put(ina, data);
+ n = NS_INT32SZ;
+ break;
