That counts only the time it takes for the firmware to load the Linux
kernel into memory, and does not include the Linux and X server startup
times.
And even ignoring the Linux startup time, we won't get to the 4-second
level unless we partition the FLASH, because of the JFFS2 mount time.
We hope that booting will be infrequent as a result of our power
management capabilities - suspend/resume will be frequent, fast, and
seamless.
