I'm afraid it is a violation. In the "Operating System Interface" chapter, "Page Size" section (page 3-23 in the copy I have), it says: "Currently, the only valid hardware page size for the PowerPC Architecture is 4096 bytes (4 Kbytes), but this ABI allows the underlying operating system to cluster pages into logical power-of-two page sizes up to 65536 bytes (64 Kbytes)." The section you quoted says that ELF binaries may use a larger congruency, not that the OS may use a larger page size. In fact the largest page size that the OS may use is the *smallest* congruency that ELF binaries may use. Of course, nothing says that you can't use kernels and binaries that are not SVR4-compliant on your own machines. But not being SVR4-compliant certainly limits their general usefulness.
