Here we go again, replying to my own post :-)

Bit of weirdness is that if I __disable__ memory remapping option in the
bios, then I get 3Gb of memory available within Linux. I thought it was
supposed to be the other way round?

When I get chance I will try adding another stick of memory and see if
that gets made available to Linux as well. Will require a shutdown of MBE
and SBE, so may be a while yet!
