The Vmware driver more simples of Bocsh VBE really.
The Bochs VBE have banking video memory and used standart VGA registers
for control.
The Vmware chip have framebufer only, don`t control by VGA-registers
and its "acceleration primitives" may be switch off by capatibiles mask
(to 0).
But Vmware chip is PCI only.

The Cirrus Logic chips have very very hard logic for emulation:
very many bits tangled expressions :-(
