I have applied the patch to the Hardy kernel (2.6.24-18-generic). It
applied cleanly except for:
1 out of 1 hunk FAILED -- saving rejects to file drivers/block/Kconfig.rej
1 out of 1 hunk FAILED -- saving rejects to file drivers/block/Makefile.rej
1 out of 1 hunk FAILED -- saving rejects to file init/Kconfig.rej

This was easy to fix (see attached linux-2.6.24.cc.diff.gz). This then
compiles fine, but I get crashes:

Jun 17 13:21:32 xp-desktop kernel: [ 5327.447776] Adding 63820k swap

See kern.log.gz for more info.

Also, I compiled compcache with "y" instead of "m" (module). This
means I cannot set the compcache size right?
