Upgrading the installation kernel for pxeboot?

I'm trying to track down a problem, and to do this I'd like to  
upgrade the kernel before installation. Going from 2.6.5 (the kernel  
that SLES9 is sadly
stuck at) to 2.6.16 (latest kernel) means that my sata controller  
starts getting addresses as /dev/sd* instead of /dev/hd*.

So, my question is, what's involved in upgrading the kernel? Can I  
merely change the kernel, and mount the intrd to change themodules,  
or is there
a cleaner way to do this? perhaps a script that exists which SuSE  
uses when they generate their installation environment?
