Well, I took the big plunge but am not able to get the 2.0 generic kernel 
(from the distribution) to boot.

Here's what I did:
1. used 1.6.1 restore CD to establish a working system on a 4GB drive
2. used 1.6.1 restore CD to install a minimal system on a 160GB drive
3. connected both drives to RaQ2, booting from 4GB drive
4. on 160GB drive left ext2 partition, removed other partitions and
   created a single netbsd partition (divided into separate 
   /, swap, /var and /tmp NetBSD partitions)
5. installed 2.0 kernel and sets on 160GB drive
6. gzipped (-9 !!) 2.0 /usr/mdec/boot loader and replaced the 1.6
   boot loader in the ext2 partition
   (the 1.6 loader gives additional messages about not being able
    to find the symbol table, etc.)
7. reconfigured RaQ2 with just the 160GB drive
8. boot loader is started and loads the /dev/wd0a/netbsd kernel
9. kernel panics during initialization
   (see kernel output below)

I see there are some additional items in the standard kernel compared to 
the 1.6.1 kernel.  Does anyone have a 2.0 kernel that'll boot on a RaQ2 
(or Qube2) that I can try?  Any other ideas?
