Have you tried manually adding the RAM?
I have a Blizzard 1230 MkII which doesn't autoconfigure the RAM, but if I use AddMem with the correct memory addresses, it works just fine.
In other words, boot with no AddMem - only get ChipRAM = very slow.
Boot with AddMem as the first thing in the Startup-sequence - Chip and Fast RAM = full 50MHz '030 speed.
You can find out what the memory addresses are by asking someone with a working CS-PPC. I have 128MB in mine - if it helps I can tell you the parameters you'll need to use to try and add the memory.
That's not to say it will work, but you have nothing to lose. Incidentally if you don't have any Fast RAM the PPC won't work, so it's just possible that using AddMem will give you a fully working CS-PPC.... I wouldn't stake anything on it though, and if it works I'd suggest buying a few lottery tickets as the same time as it'd be your lucky day!
