Octane Dual-R12K/350 (1MB), 1GB, 36GB, MXE

I finally had a chance to try the Octane CPU mod I've been wanting to do for ages, after working out the correct resistor
swap (will put up a page about this at some point). The system is just an older unit I'm using for testing. Passed all tests so
far (C-Ray, Blender, RC5, Lynx, etc. - results added! Matches a Fuel/700 for C-Ray). Naturally, the PM string and
PN code in the first main line of the hinv are now incorrect.

My plan is to offer these modded CPUs on my site for a much lower price than an original dual-400, ie. almost the
same performance but a lot cheaper. I've built two modules so far.

Note that I also moved the old 250 cores into the former single-300 modules, changed the resistor and voila,
single-250 with 2MB L2 . Works fine! I'll stick these in the lesser spec Octanes I've been getting rid of recently.

And I've modded a couple of single-300s into 350s, offer a cheaper option than single-400s.
