Thanks Donald! That certainly fixed the problem. I'm wondering
why it's not included in the shared memory howto? Is it only
applicable on certain kernel versions? Is it superceded in the
later kernels by the __va() macro? (I'm using 2.0.34, soon to
be 2.2 when my new Slackware CD arrives :-)
Many thanks!
Jim.
