I've done this on x86 with 640MB, but it requires a lot of hand tuning. You should be able to build the kernel (most likely the OPENSOLARIS issue is just moving from options.* to options, mostly), but you'll encounter resource starvation issues until the tuning is right. :( But that was in the 7.x timeframe, iirc, and that was so many ZFS revisions ago...
