..boooo: "By convention, /dev/hda1 is my root partition; /dev/hdb1 will
be the new raid volume.", to make an useful raid set, you want one disk
per controller, in your case, /dev/hda and /dev/hdc, not /dev/hdb, which
kills performance "jamming traffic" on /dev/ide0.

..I've only done this successfully with RH9, it used both Grub and
initrd, I made everything (/boot too) raid1 except /tmp (raid0), and 
put 1G of swap on both disks, both with pri=1 in /etc/fstab.

  Scenarios always come in sets of three:
