Yup, it's definitely possible with Fedora Core 3.  It contains the
necessary kernel patches and the dmraid binary.  All you need to add to
FC3 is:
- patch mkinitrd to include a static dmraid binary in initrd and run it
- patch rc.sysinit to run static dmraid to setup the mapper devices
- add /sbin/dmraid.static to your system
- build lilo with Gerte's patch

I can boot FC3 with my Sil3112 ATA Raid, and run lilo when it's running ;)

Kind regards,
