It is qemu cirrus logic "feature" of using 64-bit integers in indirect data access functions. (EDIT: 64-bit probably due to PCI bus) Direct VRAM reads or writes won't be affected if mode is linear = 256 colors or more.

I am not going to do any non-fix changes to qemu code to prevent annoying maintenance issues when/if merges needs to be done.
