Uhm, I have updated the source tree after building the kernel I'm running
now, so I can't tell. My kernel says
NetBSD 2.0_BETA (XSERVER20) #0: Mon Sep 13 08:34:08 EEST 2004
root@pyy:/ker/compile/XSERVER20
so it's not even RC1 but BETA.

My kernel was built on the 13th, but I don't know when the source was
checked out :-(

256743 pages managed
156446 anonymous pages
62270 cached file pages
26304 cached executable pages
