mysterious. we seem to have same systems, and after applying the two patches,
i haven't had any more hangups (crossing fingers ..). the only difference
seems to be, that i have set my value of MAX_KMAPENT to 2000, because when
i set it to 1000, prior to applying the second patch, it didn't solved the
problem, and i did not reset it to 1000 after the second patch.

it seems, that now i have the same stable systems as i had with late 0.0.
