this machine is in paging hell.  that's looking like about 1000
pagein and pageout requests every second.

Yep, it sure is... the disk sounds like the drum track of a sped-up techno/industrial song ;)

perhaps test/play with the vm.{exec,anon,file}{min,max} values
some?e  increase anonmin and execmin perhaps?  it is hard to
know what sort of pages are being reused so quickly..

This all worked pre 4.99.48 without any tuning and the install on this box is bog-stock (the disks from it got moved to the V120 about a month ago, and it got the then-HEAD installed on it).
