Recompiling everything is unnecessary, you only need to recompile those packages that are necessary to get your system booting with the new hardware. emerge -e system should do that, along with recompiling the kernel. As long as you have a working toolchain, you can then recompile anything important to you that fails to work on the new hardware before resetting the CFLAGS and doing a background emerge -e world while getting on with whatever you use the computer for. Don't forget to set PORTAGE_NICENESS in make.conf before you emerge -e world. -- Neil Bothwick Nymphomania-- an illness you hear about but never encounter.
