Hi.
I found a bug request at:
http://osdir.com/answers/debian/19030-lenny-upgrade-cant-mount-mdadm-raid-drive-under-kernel-2-6-26-a.html
I have the same problem after upgrading from Eth to Lenny.
There is an output from /usr/share/bug/mdadm/script script from 2.6.18
kernel:
--- mount output
/dev/md0 on / type reiserfs (rw,notail)
tmpfs on /lib/init/rw type tmpfs (rw,nosuid,mode=0755)

sysfs on /sys type sysfs (rw,noexec,nosuid,nodev)
