As this distribution is now quite old, it is more difficult to get it running with a recent kernel.
Here is a command line you can use with qemu, including the link to the bootdisk:
qemu -cpu qemu32 -clock dynticks -name RH72 -m 256 -nographic \
-hda ./RedHat-5.2-i386-root_fs
-nographic -curses
-boot a -fda ./bootdisk.img
