	Hello hendrik,

	The link below should be of help to you. Its a howto for setting up mirror 
raid 0 but its how you start the install with the sarge installer that should 
be of intrest to you.

http://nepotismia.com/debian/raidinstall/part1.html

	Start the install with the expert26 option and then pick the md module for 
the a raid enabled kernel.
