That was true from Linux 1.1.67 (when Alpha was introduced) to 1.1.84 (when __[PS]* was introduced). I'm not sure the Alpha target even worked during those versions. Since Linux 1.1.84, it has mapped pages on the Alpha without execute permission: the _PAGE_FOE (fault on exec) bit is set for mappings which don't have PROT_EXEC.
Btw, they used PAGE_EXECONLY in those days :)
