I understand the need and/or desire to do this natively but we really want to be doing cross platform for this target. 256 MB is not enough for these large compiles.

DO NOT get on Terra's Yellow Dog pre-installed PS3 list if you have not already done so. They have taken the $100 with no guarantee and they will not even hazard a guess as to a delivery date. I did not save a single dime since I could have download FC5 and IBM Cell SDK2.0 for free and done the install myself and purchased the thing from Fry's or elsewhere. IBM has a step by step procedure for doing the Linux install on their web site. Myriad videos doing disk drive upgrades, etc. are on YouTube. I am not pleased with Terra AT ALL. People are able to get one and leave the store from Fry's and do the install themselves. I do not want to wait until March so I am going to use an extra lever I have that most people do not have (think of it as the fake wheel chair person going to the head of the line at Disney World and you will understand) but this is good for one only.

I picked up a PS3 a few weeks ago, and just got Gentoo booting on it (60GB version). Out of the box, I think I set the CFLAGS wrong because the new stuff I've compiled is 32bit. I've built the cross toolchain for the SPU's and successfully ran a test program or two.

Be mindful, as Eric said, compiles are slow. The CellBE drastically dropped cost and heat by not efficiently handling out-of-order code. I don't have the link handy, but the IBM CellBE development center has a PDF intro to coding for the Cell which shows how to handle if;then;else statements in an efficient manner. Anything not coded that way will be horribly inefficient. Hence, the long compile times on a dual core, 3.2GHz processor. :(
