3) 2 partitions( tried a few different sizes) - Not OK, here I get
81ff81ff81ff ... !

You get this behaviour for both partitions? Also one that has all
sectors of the same size?

Get it to work without the viertual regions. Then add the virtual
regions if you need them. Stricly speeking you anly need them if you
have a partition that you need to manage that crosses erase region
boundary. It is hightly experimental code
that has only be tested on my single 16bit wide Intel chip so it is
bound to fail
on more complex setups.
