If I'm doing my math right, your /dev/hda is a 1.5 GB disk.  Which seems
a bit small for the issue I suspect.  But I suck at math.  Something in
th 6-12 GB range would more likely have these issues.

Usually I get this sort of message if I've got my disk geometry
configured wrong.  Read the LILO docs on specifying disk geometry in
/etc/lilo.conf or at the boot prompt.  It's cyl/sec/head or cyl/head/sec
or something like that.  See if your fdisk isn't happier after this.

Kernel version may make a difference as well, but I believe this refers
to larger disks than you seem to be dealing with.
