[Centos] CentOS 4 dual boot

Another quick question- In reading the "official" release notes for EL4, I ran across this-

Red Hat Enterprise Linux 4 support for SELinux uses Extended Attributes on ext2/ext3 file systems. This means that, when a file is written to a default-mounted ext2/ext3 file system, an extended attribute will also be written.

This will cause problems on systems that dual boot between Red Hat Enterprise Linux 4 and Red Hat Enterprise Linux 2.1. The Red Hat Enterprise Linux 2.1 kernels do not support extended attributes, and can crash when encountering them.

Anyone run in to this problem? It kind of quashes my hopes of keeping a running RH9 system sharing the /home directory with Centos 4- but what the heck.
