I think it may be the same problem that was fixed by this patch in 2.6.22: http://git.kernel.org/gitweb.cgi?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=05ec9e26be1f668ccba4ca54d9a4966c6208c611 You'd either need to rebuild the kernel (or at least jfs.ko) or move up to a newer kernel. I believe you should be able to get the 2.6.22 kernel working with ide drives. You may have to rename hda* to sda* in /etc/fstab. Maybe someone reading this group has more knowledge about this.
