as someone else already helpfully pointed out:
man groupadd
Groupnames must begin with a lower case letter or an underscore, and
only lower case letters, underscores, dashes, and dollar signs may
follow. In regular expression terms: [a-z_][a-z0-9_-]*[$]

This restriction seems to have been lifted for RHEL4 (and hence FC5)
the old restrictions will still apply on RHEL3.
This you will not be able to change.

see if your version has this in its changelog (on RHEL4)...
rpm -qf --changelog /usr/sbin/groupadd|less

it seems that groupadd uses the same settings as useradd since sometime
in 2004 - it certainly does not restrict me on FC5 at all.
I can create groups which start with an upper|lowercase letter, or a
number and they just work.

Basically, it looks like you are not going to get this feature in RHEL3
ever. On the whole, major version numbers do not tend to change for
anything over the lifetime of a Red Hat release.
