It is possible to have both root and boot on a raid partition. I've done it with raid1. I can't imagine raid5 would be any different. One way to do this is to custom compile your kernel to include all the relevant drivers you need (raid and file system) to mount your root partition. Debian stock kernels have the drivers compiled as modules, which isn't good enough. They need to be compiled into the kernel unless... You build an initial ram disk image which includes the necessary modules. Then, you can use the stock kernels. You just need to make sure the initrd was built with the modules you need. I have heard that grub might have some limitations booting from a raid partition, but I can't say for sure either way. I haven't tried with grub yet. Oh, and also, some old bioses might have problems. Otherwise, it's possible. Note that it's easier to have /boot on a non-raid, so you might set it up non-raid at first, then move the /boot partition to raid when you've got / working correctly.
