I am glad that you have got a speed increase.

You CANNOT use MacOS 8.5 -- it _very clearly_ says this on the
maconlinux.com webpage. This may be why it does not work.

You need the 8.6 ROM that can be downloaded from maconlinux.com.

This step only allows MOL to be enabled and does not automatically include
it in the kernel.

You actually have to select the options as noted by another respondant.

There is some asm-m68k source/headers needed for ppc machines. There was
a discussion of this with the release of linuxppc 200 last year. A proper
kernel source does not require any copying though...
The first time you make a kernel you have to link two or three directories
together, I forget which. I believe that that should be done
automatically with modern kernels though.

Conventional to also make modules && make modules_install for any modules
selected in your xconfig/menuconfig step

That pretty much means that the kernel you used did not include support
for MOL... This would suggest that you did not enable MOL in the xconfig
step. For me using menuconfig there is an additional main entry entitled
MOL of Mac-on-Linux or so, and that needs to be enabled.

It seems you were caught in a case of poor use of English - MOL talks
about patching a running kernel, but simply "patching" the kernel source
does not automatically include that "patch" into the compiled kernel --
sorry.
Good luck.
