I must admit, I hadn't considered this, but on consideration, I'm
pretty sure I saw socketed ones - if only because for a while,
replacing a 386SX with a 486SLC was a popular upgrade option.
WikiP seems to bear me out:
http://en.wikipedia.org/wiki/80386SX#The_i386SX_variant
"The 386SX was packaged in a surface-mount QFP, and sometimes offered
in a socket to allow for an upgrade."
Yes, they were Quad Flat Package things, but QFPs came in a socketed
form sometimes - I fitted a few of them myself, even though I was/am
primarily a software guy.

To my recollection, the 386SX only came in surface-
mount packages. The N8VEM folks (including the S-100
group) have done a pretty good job of making sure all
their boards can be assembled with only through-hole
parts, which makes it a lot easier for novice solderers
with cheap irons.
This is an ongoing project. It utilizes the 16 bit mode of the 80386 to
address the 16MG of RAM the S-100 bus is capable of addressing.
Just out of curiosity:
Wouldn't an 80386SX have avoided this restriction and been much easier?
