This is sort of right. /dev/cuaxxx are in most cases the wrong choice
because they implement kernel level locking. What was happening was
that once one process (gpm) opens /dev/cua0, the kernel does not allow
another process (X) to use the same device. The /dev/ttySxx are
specifically not designed this way. They are designed with the idea
that intelligent programs will take care of their own locking (which
gpm and X do nicely) so more than one program can share the same
devices.
