Just how "official" the parameter really is? The problem is, you want
root on reiser to be in notail mode (if you boot off root - in any case,
to avoid problems with bootloaders) and remounting reiser later AFAIK
does not change tail conversion mode.

The rootflags parameter is only a part of the ext3 patch, AFAIK.  It
is therefore probably in -ac kernels, but not stock Linus kernels.
Since it is useful by itself, it may be good to submit it as a patch
to Linus (this was done once along with the rootfstype= patch) but
I don't think it made it in.

Cheers, Andreas

Ah ... well, in this case I speak about Mandrake kernel that includes
ext3. Thank you.
