No I haven't tried that yet because I hope that there is
be another way to solve this... Moving those chips is
anything but fun. 
But if NetBSD really uses burst mode why it doesn't work
when I  force loadbsd to only use my Static Column memory 
(1st 4 megs) by using -m option? 

By the way, I can get that white screen (it's the screen that
comes after loadbsd has been started; after that should that
NetBSD screen appear)  also when Kickstart has been loaded
in  memory earlier and I boot to that KS switcher (with  
ROMboot util if I remember right) and then try to loadbsd
using  KS 1.4beta. I hope the someone got that...
