I don't know exactly, but remember that we only turn off
automatically detection of the amssymb package but not the amsmath
package to keep documents compilable.
If this is the case it is a bug IMHO. In earlier versions of LyX, if the
user set the ams math switch to off, amsmath was not loaded at all, even if
that would make the document uncompilable. The reason for this behaviour
was to solve problems like the one reported. There are a couple of commands
in amsmath that are also provided by other packages, and in some cases
those other packages are wanted.
OK, then it is really a bug: http://bugzilla.lyx.org/show_bug.cgi?id=5350
I fixed it now for LyX 1.6.0.
