i am using the kernel patch and have CONFIG_EXT2_RESIZE.  i have had
problems with resizing when i resize several filesystems repeatedly by
small amounts (that is always my preference, rather than giving one big
boost that may waste space).  at the time i had difficulties the root was
full (except for space reserved for root), but i don't know if that is
relevant.  unfortunately, i've got no specifics to report, but i'll try to
reproduce it today.

interesting.  i will recompile, recompile, re-lilo and try again.  this
really *was* working with that kernel before. sigh.  this is helpful to
know, though.

yes.  i put vgchange -a y and vgscan in /etc/rc.sysinit (it's a RH box)
and that seems to be working well for now without the LVM root, but given
the problems i've had with /etc, i will recheck the faq and try again.

again, thanks for the help.
