turns out huge unreal mode isn't supported in bochs
...
huge unreal mode is 4GiB code in 16bit mode + 4GiB data
we will just use the regular big flat model instead (64KiB code/4GiB data)

big step...and also its completely broken right now
...
we are going to use 0x07E0 as our base segment so we have a bit
more memory to work with until we are fully in 32bit protected mode.
this commit is broken but is just one step towards a working release.
