Hint: upgrade. These days it is either 9.1.3 or 9.2.0rc3 (which by the
way works great for me, though I haven't exactly stressed it
artificially - but it is a master for several zones).

BIND 9.2.0rc3 has no problem with this zone as you posted it:
[michael at varg michael]$ /usr/sbin/named-checkzone -v
9.2.0rc3
[michael at varg michael]$ /usr/sbin/named-checkzone 48-28.62.216.193.in-addr.arpa 48-28.62.216.193.in-addr.arpa
zone 48-28.62.216.193.in-addr.arpa/IN: loaded serial 2001092100
OK
[michael at varg michael]$

Well then, there is your problem. You are pointing BIND at a directory
where it expects a regular file. Also, I strongly suspect that you
don't have any directory /path/tofile on your system, whether in a
chroot jail or not.

SERVFAIL is normal when there is a syntax error in the zone file, or
it could not be loaded for some other reason (file not found, for
example). It just means "server failure".

Fix your named.conf.
