Your problem with the keypad enter is actually a problem with all Speakup keypad functions in the 3.4 and 3.5 kernels. In all these kernels, pressing any Speakup keypad key causes the kernel to crash and burn, and the system must be hard rebooted in order to get things back up and running. There are two possible solutions to the problem. Either use only laptop layout keys, e.g. capslock enter, or install Linux-lts and edit syslinux.cfg to point to the linux-lts kernel, e.g. vmlinuz-linux-lts and initramfs-linux-lts.img. I'm somewhat at a loss trying to solve the enter to boot problem, but it's possibly not related to the bootloader. It may help to find out just how far your system is actually booting before you press enter to get a talking system. You should be able to navigate the Speakup cursor above the login prompt to find out any prompt that was printed to the screen before you pressed enter to get it talking. Hope this helps. ~Kyle
