It is, it's *exactly* like doing it with any other software raid.
The only real issue is bootloaders. At least on FC/RHEL, we haven't
made modifications that would be required to boot off of a logical
volume.
In FC4 we do support /boot on a RAID 1, so if you're doing dmraid with
raid1, it should be possible to put a 100M partition for /boot at the
beginning of the raid, and then build your PV on the rest. (that is,
you can do it exactly like the default install now, but with a raid1
underneath).
Hopefully, we'll be able to do more support in the future, but it's
complicated and not really on the immediate roadmap (read: it's not on
my schedule).

It's more than just the installer -- initrd needs support, as do
mount/fsck (think "fsck -a"), and almost certainly initscripts will need
some work as well.
