if memory serves...

1) create /dev/hda1 with type Software RAID autodetect and size 100M
2) create /dev/hdb1 with type Software RAID autodetect and size 100M
3) click the "RAID" button and create a RAID 1 volume, /dev/md0,  
using those two partitions
4) format /dev/md0 as ext3 with mount point /boot
5) create /dev/hda2 with type Software RAID autodetect and size <the  
rest of the disk>
6) create /dev/hdb2 with type Software RAID autodetect and size <the  
rest of the disk>
7) click the "RAID" button and create a RAID 1 volume, /dev/md1,  
using those two partitions
8) format /dev/md1 as Logical volume
9) click the "LVM" button and create a new volume group containing / 
dev/md1
10) create logical volumes within this volume group as necessary (i'd  
recommend at least swap, /var, /)

proceed with your install.  when finished, you've got one more step  
after you reboot; you need to copy grub onto the MBR of /dev/hdb.   
here are instructions:

somebody else may have written this up on this list before.
