install Etch with raid level 10

[Scott Lair <scott@lairhome.com>]

I tried to install Etch on AMD64 using raid level 10.
After I partitioned the drives, I went to create the
md devices and could only choose from raid levels 
0,1 or 5.  Should I be able to install with level 10?
I tried the latest netinst.iso and the cdrom install 
disk 1 with the same results.

thanks,

scott
