What about VMWare support for x86_64? I have a T61 with the Core 2 Duo Merom and 4GB of RAM. I'm currently running Ubunutu 7.04 32bit on it and will likely move to 7.10 when it comes out. Right now I basically run VMs on top of it, so I barely touch the underlying host OS. Does anyone know if moving to 7.10 x86_64 cause any issues with VMWare?
