Default KVA_PAGES & nVidia Driver

Hi!
According to http://wiki.freebsd.org/ZFSTuningGuide
users of FreeBSD 7.0 should increase KVA_PAGES to 512 in kernel config to make ZFS usable on i386 platforms (otherwise with intensive disk i/o kernel will panic with kmem_map too small message), but after increasing KVA_PAGES to 512 nvidia drivers starts to incorrectly output video overlays (green window instead of overlay video), the most strange thing that this behaviour could only be seen after 2-3 hours (sometimes 5-6) of box uptime. This can be easily checked with mplayer -vo xv or gl2 . This is "stable" bug, checked at 3 boxes, with different hardware specs.
