Probably, you have created your file-systems in the new format. You can boot 2.4 kernel, create new file-system large enough with /sbin/mkreiserfs -v1 (old format), copy existing files there by tar or cpio and then update /etc/fstab to mount file-system just created. Now, you can work both with 2.2 and 2.4 kernels. Keep in mind, that 3.5 format has some limitations concerning file size etc. Check faq at namesys.com for details. On the other hand, 3.5 often considered more stable. Nikita.
