I retried to boot and here's the error that I'm getting:
EXT3-fs: unable to read superblock
cramfs: wrong magic

I decided to resintall devfsd to correct that problem. I think it 
helped, at least I'm seeing ide/host0/... everywhere now.

One thing that's strange is that mdadm doesn't seem to recognise 
/dev/md0 (or /dev/md/0) but it's clearly mounted and working...

gfk@ali:~$ sudo mdadm -D /dev/md0
mdadm: md device /dev/md0 does not appear to be active.
gfk@ali:~$ mount
/dev/md/0 on / type ext3 (rw,errors=remount-ro)
/dev/ide/host2/bus0/target0/lun0/part1 on /boot type ext2 
(rw,errors=remount-ro)
proc on /proc type proc (rw)
devpts on /dev/pts type devpts (rw,gid=5,mode=620)
tmpfs on /dev/shm type tmpfs (rw)
gfk@ali:~$ cat /proc/mdstat
Personalities : [raid1]

After reinstalling devfds, fdisk -l is working:
gfk@ali:~$ sudo fdisk -l | fgrep raid
/dev/ide/host2/bus1/target0/lun0/part2   *        1276      155061 
77508144   fd  Linux raid autodetect
/dev/ide/host0/bus1/target0/lun0/part2   *        1276      155061 
77508144   fd  Linux raid autodetect
