..this is a stock Woody?   Grub?  Or backports.org?  
(If still down, try uk.backports.org.) 

..I got into the same mess on my first Debian box, /dev/md0 worked fine
with RH9 on the same box, but this happened to be pre-Fedora time.

..the box can boot off all raid disks from bios? /dev/hda+/dev/hdb etc 
will do fine, except for the wee need of another lilo run fix on the
2'nd disk, to avoid that, use grub.

..I used grub, see above.
