Historically, Macs have pretty much *always* been able to take the bigger
chips when they come out, and Apple *always* specs them at current market
limits. It's possible that this is an exception, but I'd put my money on
the support being there. Besides, there are normal DDR (not DDR2) 2GB DIMMs
now, so those don't require a newer architecture, just support in the
chipset. There are a couple of vendors selling 2GB DIMMs labeled for the
Xserve out on the web, and The Xserve is also speced by Apple as having a
max of 8GB of RAM, so I'd bet that 16GB is possible today.
