Patch 1 fixes the problems I was having with RAID-1 arrays not able to start up 
on 2.6.17-rc4-mm1.  Thanks for that.

However things appear still not quite right on boot, as each mount works but 
displays as though it didn't work, ie:

md: considering sdc2 ...
md:  adding sdc2 ...
md:  adding sda2 ...
md: created md0
md: bind<sda2>
md: bind<sdc2>
md: running: <sdc2><sda2>
raid1: raid set md0 active with 0 out of 2 mirrors

0 out of 2 ?

cat /proc/mdstats  shows that everything does in fact seem to be working:

md0 : active raid1 sdc2[1] sda2[0]
      24410688 blocks [2/2] [UU]
      bitmap: 21/187 pages [84KB], 64KB chunk

The array otherwise seems to be fine.  I guess it's just a visual glitch.
