Where did it appear in 'beosetup'.

If it appears under 'unknown' you have to drag-n-drop it into the
center column. Then press the apply button.

The kernel source that is in /usr/src/linux is bproc-patched.

It's mostly a compile-and-go exercise. You can make the nodes use this
new kernel by editing /etc/beowulf/config and running beoboot -2 -n
to regenerate the phase-2 boot image.
