RedHat's position may be influenced by the fact that, AFAIR, they use the Rik van Riel virtual memory system which is inclusive--i.e., you need at least as much swap as you have physical memory before you really have any virtual memory at all. This was fixed by the competing Andrea Arcangeli system, which became standard for the Linux kernel around 2.4.10 or so.
