Well yes, in 2.2.10 someone tried to add CONFIG_PPC64 support in to 2.2 
kernel.
In 2.2.11 someone add CONFIG_PPC64 in to Config.in! but on 2.2.12 or 
2.2.13 someone remove it ... 
(without remove it from directory != arch/ppc/kernel/ )

I used g3 (pmac). My based system was PLD with 2.4.18 tree.
I used gcc-2.95.4 to build 2.2.21 vmlinux.

I tried to fix problem witch is on my IBM RS/6000 (model b50).
Openpic can't initialize propertly my scsi system. (sym82c8xx scsi 
driver). Some time init problems.

Oh I forgot, 2.2.22rc1/2 or kernel >= 2.2.16 (2.2 tree) didn't work on my 
IBM RS/6000 (b50).
Build with egcs work, but work slow (Bogomips: 16MHz!) and won't reboot 
and shutdown -h now.
The same code build with gcc Ops (Kernel Exception, look like openpic 
allocation address.)
I'll post the Ops later.

Hmm, yes, that why my patch is ugly. I want to do this correctly.
