Not able to boot a software raid installation - Ubuntu 10.04.1 i386

[Dan Sheffner]

I used to have problems booting software raid with ubuntu 8.04.  The fix I
found was creating a third device for /boot/ partition.  512MB is plenty big
for the /boot/ partition.

So my structure was like this:
/dev/md0 /boot/
/dev/md1 Swap
/dev/md2 /
