No reason why not, but plenty of reasons why you'd want to use a 386 or
something similar instead (i.e. twice as fast and 1/10th as expensive).

I'm pretty sure they removed multiprocessor support to make the kernel tree
smaller. Why would you want to cluster them to begin with?

All the *chips* are on one side, but there are a couple SMDs on the back.

Seriously, if you need a cluster, the uCsimm is about the least economical
way to build one. Think about it. A uCsimm costs nearly $200. You can get a
486/100 that will run about 20 times faster (the chip, motherboard, memory,
etc.) for about $100. And that 486 has the ability to offer memory
protection and native floating point math. Believe me, we had this argument
on the list about half a year ago. Building a uCsimm cluster might be a cute
science experiment but it would be extremely impractical, both in terms of
horsepower and money.
