Seeing how RAID-10 is still experimental in the kernel, the installer will 
probably not support it for awhile.  I'd suggest you either install Debian 
onto a single disk and then migrate the data to a raid10 or boot off of a 
CD that has raid10 support in the kernel, create your raid and then 
restore the data onto the raid10.
