Hmmm... maybe I'm going about this the wrong way.  Would it make more
sense to get rid of the LA on that side, move the sdram chip as close
as I can to the FPGA, and use something like chipscope to monitor the
signals?  I've got both SPI and addr/data connections to the MCU on
the other side to get the data out.

Yeah, but that's pushing the project outside the effort I want to put
into this board - basically, it's a one-time board to try some things
with.

> Here's another idea.  Instead of the LA, use a scope

My scope is nowhere near fast enough for that.  The LA is 500 ms/s or
can be externally clocked up to 200 mhz.  The scope is only 32 ms/s.
