Hi All,

when I read this first I thought "easy" (having in mind cat-ting "4"
somewhere into some file in the proc tree), but this is a kernel change
and recompile. I do not have the sorces on the machine and do not realy
know how to crosscompile on my i686 box. Trying to ftp the kernel source
over will panic the kernel.
I looked into the kernel Makefile, but am not sure what changes to do
there. Is there some info on that? (I'll look up the website for
x-compilation). All this seems to be over my intelectual limits. ;-(
Is there a chance to change that default value in the precompiled
kernels??

Juergen
