OK, that's what I was looking for.

Ah - if I recall correctly, 2.4.x kernels can't do autodetect for RAID5. I
could very well be recalling incorrectly, though.

Is mdadm or raidtools being started on bootup? (Check your init scripts.)  
That should be able to figure out the array and get it going, even if the
kernel autostart didn't.

If you're using raidtools, you might want to switch to mdadm - it has the
nifty ability to e-mail you when a drive goes belly-up.
