After some tinkering, it turns out that the VXL-30 can be re-configured to map 
the RAM in a "high" mode which enables the GG2+-card to be configured properly. 
This presents a whole slew of other problems though, since the VXL-30 refuses 
to boot properly without running the "setvxl" tool, which in itself is pretty 
straight forward.  It still doesn't work properly though: I cannot run setvxl 
and the parameter for enableing all the extra RAM connected to the VXL-30 in 
either user-startup or startup because the Amiga will just throw a guru 
medition on me before workbench is even booted. 

So to be able to use my Amiga 2000, at the moment, with my GG2+-card, I have to 
boot the Amiga without startup-sequence, run the command I need to enable the 
RAM, reboot the Amiga with startup-sequence enabled and then it boots.  I 
cannot use burst mode or cacheing in the 030 because then the amiga will crash. 


I'm waiting for a TF530 board that I will place in my A2000 instead and this 
card will either go on sale or in the kids A500.  

More testing to be done though so fingers crossed.
