Basically, you don't want to set up a zone for 67.158.193.in-addr.arpa in named.conf, but rather for something like 64-71.67.158.193.in-addr.arpa. Googling for "bind classless in-addr.arpa" and related strings will likely answer your questions. If not, asking for help in comp.protocols.tcp-ip.domains might help.
Ah, thank you very much, this sounds very helpful! :) I´ve been googling on the topic and looked through the Admin Guide, but didn´t find what I was looking for. Seems that ´classless´ is the crucial keyword.
