ETA System V supported variable page sizes of the form supported by the
ETA-10 hw.  This was two flavors of page, "small" and "large" - both were
selectable at boot time.  "small" was 16 or 64kB; "large" was 512kB or
2048kB.  (n.b., the 2048kB aka "giant page" was not officially supported
or tested).

If this is what "variable page sizes" means above, then yes.

An arbitrary a.out could use both sizes simultaneously.  Typical use was
small for text, large for data and bss.
