I am not exactly sure what is meant by "dual channel IDE bridge;" does
it mean two channels with each supporting a master and slave? if the
enclosure is advertised to support 4 drives, then it should work fine
using the correct version of Linux.

I recommend, in order to retain closest match to RHEL kernel but get
this key functionality, copy the drivers/ieee1394 directory from a
2.4.22 kernel source into your RHEL kernel source tree and then build
your modules. I can't vouch for the latest revisions of ieee1394's 2.4
branch, but I know what we have in 2.4.22 is very solid and closest to
the kernel version Red Hat's kernel is based upon.
