The kernel needs to mount the root filesystem before it can read /etc/fstab, 
which means it needs to rely on the filesystem flags to determine what type 
of filesystem it is. You need to tell that partition that it doesn't have a 
journal, which in effect makes it ext2. This command should do it:

tune2fs -O ^has_journal /dev/hda2

(using the correct partition, of course). However, to make things really 
tricky, this can only be done on a filesystem that is umounted or read-only. 
I think you mentioned you were running out of a temporary root? You might 
need to use this, or boot off a rescue CD or something. On some 
distributions, booting into single user mode can also lead to a ro root 
filesystem, but I haven't seen that in a while.
