I see the message `Press <RETURN> to see the video modes' with a list
of 6 video modes, then `Enter mode number or `scan':'. I tried `scan',
which led to losing the video signal for nearly a minute, then it came
back with a cleared screen and a list of 7 video modes. After entering
number 1 I got `the famous boot stall'. 

Does this vga=ask action come from isolinux.bin code or from vmlinuz
code?  Do you have any other suggestions for command line twiddling?
