Use a kernel with ext3 support. AFAIK ext3 is only in kernels >= 2.4.15.
If this is a RedHat kernel upgrade to the latest errata kernel.

If you are sure that there is ext3 support in your kernel, check that
ext3 and jbd are compiled into the kernel or, if compiled as module, are
in the initrd image.
