I'm having the problem again.  This time, I'm using 2.6.35.4.  Would
changing from 1gb kernel/3gb user to 2gb/2gb help?  I don't believe I
actually use more than 1gb or so of user space memory anyway.

64-bit would require that I completely reinstall this system which is
definately not something I want to do.
