IMHO it would be more efficient to get IBM and Novel to address the issue and eliminate VDISK memory creep without having to configure multiple VDISKS with different priorities.
If memory constraints can be addressed in z/VM 5.3 with z9's (CMM) why can't the above issue be resolved ?

Indeed. That's the entire trick: force Linux to use all free space in the first swap device before using the next one. Note that this is exact opposite of what "them from the other platforms" use with multiple swap devices (to spread the load evenly over multiple slow devices).
