Please don't, this reminds me of a situation where I didn't yet use
the raid-patches. I had used a mirror on two IDE disks. Initially,
because one disk was ca. 16MB bigger than the other, I used the extra
space as swap. Later, I removed that swap partition. That's when
ominous failures began when I tried to access that mirror... Quite
some time later I found out that something unloaded the IDE module
from the kernel while the mirror was running on those IDE disks!!!
