I haven't tried it with Grub yet, but I would expect it to fail in the general
case. As far as I know (and do please correct me if I'm wrong) Grub installs
a minimum on the actual MBR, while LILO will be placing the whole initrd
image there.
That said it might work on RAID1 partitions, since the component devices still
can be accessed by Grub as normal ext2/ext3/xfs/whatever partitions.
The actual problem regarding the kernel installation, is that the
mkinitrd-script finds MD devices present. Therefore it would like to include
some kind of tool to enable those (mdadm is my choice, it could as well be
raidtools2). And this is all done in one of the configuration scripts of the
kernel packages.
The simple solution is of course to install mdadm as part of the base
installation, but people not needing it might get annoyed by that.
However, I'm going to look into the "install-by-need"-process as soon as I get
some time again.
