RHEL 4 does not include Xen as far as I know so you cannot be using a 
RHEL 4 kernel.

Not sure what lssd does, have you tried "modprobe qla2300"?

Make sure that you are running the -xen version of the kernel, not the 
-dom0.
Did you build the QLogic divers as modules or compiled in?  We have 
functional qla2300 drivers using Xen kernels.
There's a good chance that you have a config file for your kernel in 
/boot/config-VERSION.  Do a "grep QLA2300 /boot/config-`uname -r`", you 
should see one of the following:
  CONFIG_SCSI_QLA2300=m
  CONFIG_SCSI_QLA2300=y
  CONFIG_SCSI_QLA2300 is not set

If you see "m" then your running kernel should have a module available 
to it.  You can confirm this by looking in your filesystem, for example 
with the following find command I can print the file location on my system:
  # find /lib/modules/`uname -r` -name qla2300.ko
  /lib/modules/2.6.12.6-xen/kernel/drivers/scsi/qla2xxx/qla2300.ko

If you see that you configured with "y" then the driver should be built 
into the kernel and you would see some files under sysfs which tell you 
that your QLA is seen, try this:
  # cat /sys/class/scsi_host/*/isp_name
  ISP2312
  ISP2312

If you don't have such files then your driver is not active.

I would assume that the driver simply is not build into your running 
kernel.  Rebuild your kernel using the CONFIG option as documented in 
the README file.
