The driver reconfigures DRAM size register to 8M (regardless what the
actual size was) once the init has been completed, overwriting the
correct value written during the early init. As a result if the driver
is unloaded and reloaded, the user will be limited to 8M video memory
and may lose some of the available video modes.
