I'm seeing the same thing with the uCsimm modules I just received
which have the same uCbootstrap v1.04 and FLASH type 00c0 [AT49BV1614]

If the bootloader can't set the variables, it's a pretty good guess
that flashing images won't work. It seems like there must be a problem
with this rev of uCsimms.

I still have a number of older uCsimm modules that work fine, so I
can get by for a while, but I hope Lineo gets a fix for this soon,
before I run out of the older uCsimms.
