Hi Zach
It takes a _long_ while to get to raw serial console login prompt of a stripped-down ubuntu nano image. On my core i7 (first gen) the simulator can sometimes reach around 1M instructions per second but is usually slower. On top of that I don't know if it has any kind of support for graphics.
We've noticed that for some reason running MAKEDEV takes seriously ages, so if you don't have CONFIG_DEVTMPFS enabled in your kernel, make sure you turn it on in the kernel config. This causes the bootscripts to bypass MAKEDEV.
You may also find that the model uses a lot less RAM if you turn adress space layout randomisation off -- something to do with the way memory mappings are cached:
echo 0 >/proc/sys/kernel/randomize_va_space
This is especially helpful on machines where the memory usage would otherwise run into swap.
