The X-server (<= 1.3.0.0) needs basically 2 things:

* networking
* tty*, fb* entries in /dev

So you could move starting the X-server way forward in the boot order.
Note that userland needs dbus (and kdrive 1.4), so putting
xserver-kdrive-nodm-init right after dbus should work.

Check your kernel defconfig, it probably has a gazillion virtual
consoles, decrease those to like 8 and udev starts up almost
instantaniously. Related to that, more recent udevs use a different
method to create devnodes which is said to be faster.
