Okay, I tried current kernel and now network doesnt work.
doing just ifconfig -a gives this:

ifconfig: socket: No buffer space available

on:
NetBSD foo 3.99.21 NetBSD 3.99.21 (XEN3_U) #0: Fri Jun  9 01:12:44 UTC 
2006  
builds@b3.netbsd.org:/home/builds/ab/HEAD/i386/200606080000Z-obj/home/builds/ab/HEAD/src/sys/arch/i386/compile/XEN3_U 
i386

sigh. :-P
Anyway, theres no high loads anymore but network connectivity would be cool.
