Unfortuantely, I'm pretty sure that if you run such a kernel and call $BIGISV for support you'll find yourself in troubles. :-( For example, at least one important ISV even requires a specific version of the distro kernel RPMs (excluding security updates), so I pretty much doubt they'll support an alternative kernel such as one with 64K page size. > I just think that we should validate the 64K page size more rigorously. > So as to have the OSVs gain more confidence.

For example when we also consider CPU counts we get 32p vs 512p maximum on one dimension, and 16K vs 64K on another, and there may be further ones lurking in the dark right now (like Xen Dom0 versus Xen Dom1). OSVs and ISVs, on the other hand, usually prefer to only test and harden and qualify/certify a single kernel (which is why Dan's approach to Xen/ia64 looks quite appealing).
