Two RAID questions

I had a bad weekend here a couple of weeks ago, when all three of my
computers went on the fritz over the course of three consecutive days.
I now find myself in a position where it would be nice to recover
some information. I lost no hard drives (that I know of).
First; I have a Fiesty box where the OS is installed on an EIDE hard
drive. It also has a SATA RAID 5 array. mdadm is managing the RAID 5
array. I will be replacing this hard drive with a different one in
the near future. I plan to do a clean install on the replacement HD
using Gutsy. Is there anything that I should get off of this system
(the EIDE drive, or the array) before I pull the old drive? Will I be
able to bring the raid array back up under a new install of Gutsy?
Second; and in fact more important. One of the other systems to die
had a RAID 0 being managed by the MB (it was a Silicon Image
controller; SiI3112). The MB died. Can Ubuntu rebuild this array so
that I can look for any data I might want to keep? I'd been backing
this system's data up to the RAID 5 array mentioned earlier, so I
don't believe there is anything I can't stand to loose.
Thank you for any information you can provide.
