Yes, except that grub-0.5.96.1 has a problem with 3.6.x symlinks
(fixed in CVS).

This normally means that this file is written with tail compression.
The notail option only applies to new files, so you should rename
and copy reiserfs_stage1_5 while reiserfs is mounted with -o notail:

  cd /boot/grub
  mv reiserfs_stage1_5 dummy; cp dummy reiserfs_stage1_5; rm dummy

Or just remove reiserfs_stage1_5.  It doesn't make sense to use
stage1_5 if it can't be embedded (fixed in grub CVS).

The other solution is to upgrade to the grub CVS version, which
automatically makes use of the reiserfs bootloader area.  This way
reiserfs_stage1_5 can be copied there and grub works even with tail
compressed files.
