I have *never* lost my X session because of this -- it either
completely locks the machine, or everything continues to work
normally.  I suspect you might be seeing something different.

Nope, this does not qualify.  I probably get hundreds of drop-outs a
month.  They never cause badness.

It only happens when I power the (external) modem off and back on.
And it doesn't happen every time, only occasionally.
