Yes.  You can boot from SAN manually by typing

  sanboot <root-path>

at the command line, e.g.

  sanboot iscsi:

You could also include this line in an iPXE script.  At present, there is no 
easy way from the command line to do a combination SAN+filename boot (in which 
a SAN device is hooked and a filename is booted).  This will change as soon as 
I have worked out a sensible command syntax for "hook SAN device", "unhook SAN 
device", etc.
