reiserfs root fs broken: 2.4.22, 2.5.68+

In 2.5.68 (first dev kernel I tried) and beyond, remount of reiserfs
root filesystems is broken. Whatever caused it has also been backported
to 2.4.22. I assumed someone would notice, but since it's still present
in 2.6.0-test7, that is obviously not the case.
mount claims the partition to be mounted rw, though the kernel was
booted with the ro option and returns EROFS for any write attempts on
the partition. Any attempt to remount fails with "/ not mounted already,
or bad option". Booting with ext2 initrd gives the same results for
Previous exercises with 2.5.70 showed that recompiling util-linux to
explicitly include the development kernel's headers did not solve the
Mounting and remounting reiserfs partition at anywhere other than the
root works flawlessly. Mounting ext3 as root also works fine.

If nobody knows what the problem is offhand, I'll try finding it myself.
(Google found some previous reports of this issue, but no
patches/solutions/workarounds.) Hints appreciated; this is my first
major foray into kernel source.
