It wouldn't be particularly difficult to add support for x86_32 systems with more than 4GB, but would be a fair amount of work and isn't very high on our priority list. The PAE36 3-level page tables are all a bit of a hack, and we'd much rather put our efforts into x86_64. I don't reckon there are that many x86 systems with more than 4GB in use right now, and everything on the market will be x86_64 very soon anyhow.
