Description of problem:
If I've configured my system for serial console by adding "console=tty0 console=ttyS0,9600" to the kernel arguments it'd be nice if the necessary options, "com1=9600n8" in this case, were added to the xen kernel line when I install kernel-xen. It currently copies over the options to the vmlinuz module line but the options for xen are necessary as well.

I may be overlooking a better way to do, not sure.

Version-Release number of selected component (if applicable):
5.3

How reproducible:
100% 

Steps to Reproduce:
1. Install RHEL 5.3.
2. Configure the system for serial console access by adding "console=tty0 console=ttyS0,9600n8" to the kernel line, updating inittab, securetty, etc.
3. Install kernel-xen
4. Reboot into the xen kernel
  
Actual results:
Kernel options are copied to the vmlinuz module line, however the xen kernel does not get the necessary options.

title Red Hat Enterprise Linux Server (2.6.18-128.el5xen)
        root (hd0,0)
        kernel /xen.gz-2.6.18-128.el5
        module /vmlinuz-2.6.18-128.el5xen ro root=/dev/myvg/rootvol console=tty0 console=ttyS0,9600n8
        module /initrd-2.6.18-128.el5xen.img



Expected results:
Add com1=9600n8 to the xen kernel line too, ie:

title Red Hat Enterprise Linux Server (2.6.18-128.el5xen)
        root (hd0,0)
        kernel /xen.gz-2.6.18-128.el5 com1=9600n8
        module /vmlinuz-2.6.18-128.el5xen ro root=/dev/myvg/rootvol console=tty0 console=ttyS0,9600n8
        module /initrd-2.6.18-128.el5xen.img


Additional info:
Filed against mkinitrd since that seems to be where the magic happens via new-kernel-pkg
