Hi Adrian,thank you very much for your suggestions, I will surely join that IRC channel.
I would like to add to my previous message that our main architecture target is PPC64BE with Altivec, without VMX as we are currently carrying out a project for an open hardware design of a laptop based on a low power consumption CPU T2080, wich is a Freescale/NXP e6500 64bit book3e with Altivec.
Regards, Roberto
