No, OS X ACLs are not standard POSIX ACLs, and cannot be directly sent
to an incompatible host. You can instead tell the receiving host to use
--fake-super, which will store/retrieve the ACL information as an xattr
(among other things). This incompatible ACL data is the cause of this
error:

That number is nonsensical to a POSIX ACL system, such as Linux.
The next error you cite is a limitation of your file system (probably
ext3) in how large the extended attribute data can be:

If lsetxattr() is complaining, there's nothing rsync can do about it
(not without outside assistance).
A helpful user here, Wesley Terpstra, posted a solution that uses an
LD_PRELOAD library to redirect the ResourceFork xattr data into a DB.
Look for the posting with the subject "Linux backup server LD_PRELOAD".
(I haven't tried it, but the code looked good.)
Another solution is to choose a different filesystem, such as (I
believe, but double-check to be sure) xfs.
