You shouldn't need to pass any options.  All you need to
do is make sure that once your RAID-1 root filesystem is
created and mounted that you copy your /etc/raidtab to 
/mnt/gentoo/etc/raidtab, and that after the chroot process
you compile a new kernel and install it (with RAID-support
built-in) before you unmount all filesystems and reboot.

As long as your RAID partition has partition type "FD",
it'll be detected and started automatically at boot time.
Just use this line for GRUB:

kernel root=/dev/md0

...and you should be all set.  Of course, I haven't gone
into detail and haven't tried it myself, but it should work.
I should be able to try this in VMware in the next few days
and add the necessary steps to the install guide.
