Congratulations for your analysis so far!
I assume you were doing the selections for 'Field editable from profile' (in fact /modules/profile/admin/permissions.php?op=edit) and that
print_r ($_POST); // shows what variables are posted
exit(); // stops further processing
was inserted after <php and before include?
Did you tried the operation with different browsers (eg FF and IE)?
When the form shows (/modules/profile/admin/permissions.php?op=edit), could you do a view html source in your browser and cut out the part starting with
<form name="groupperm_form" id="groupperm_form" action="http://yourhost/modules/system/admin/groupperm.php" method="post">
(search for groupperm_form) up to the next
</form>
If you save this selection in a file for the local and one for the hosted system and you do a file difference on these two results, are there any differences?
(List only the differences if any other than the hostname in the action parameter at the begin of the form.

Any ideas what can cause this on one server and not another?
In principle there should be no problem with length etc for POST variables. Maybe check once carefuly the result of phpinfo(), there might some limitations that differ for POST (look also in the Apache Suhosin section (if present)).
