As far as I know, the ACL support for ext2 was planned, but never achieved, and now dropped, because an ACL field in the indode structure has been used to allow files bigger than 4GB. See the file: linux/include/linux/ext2_fs.h. It contains the following line:
#define i_size_high i_dir_acl
Which means that you cannot have ACL and +4GB files in the same time. This second feature has been considered more useful than ACL. I think that it is not feasible to keep backward compatibility with older ext2 filesystems and get ACL and big files in the same time. Maybe it is time for an ext3 filesystem ?

PS: however, another filesystem might be just what you need. Maybe ufs ?
