Comment:

 For a quick experiment, I added the following lines on top of rc.sysinit:

 {{{
 mount -n /proc
 mount -n -o rw,
 mount -n /sys
 mount -n -t usbsfs none /proc/usb
 mknod /dev/mem c 1 1
 cat /proc/uptime >/time1
 /usr/bin/startx
 }}}

 Then, in /.xinitrc:

 {{{
 cat /proc/uptime >/time2
 }}}

 From this, I gathered the following information:

  19.80 - rc.sysinit started
  23.91 - X server started

 X takes roughly 4 seconds to load.  It takes less than 1 sec when the
 pages are already loaded in the buffercache.

 Running xinit directly instead of through startx is likely to improve
 things a little more.

 We could reduce this time even further with X 1.4 because the footprint of
 my custom server is somewhat smaller.
