I have posted sets of 2.6-based systemimager RPMs built on ia64/RHEL3 and i386/FC2. They can be downloaded here:

I'm not guaranteeing that these work, and I'm not guaranteeing that they won't cause your box to burst into flames. Use at your own risk. That said, they should work fine and if they don't, email me (and the list I guess). I will be testing quite a bit more on i386 and ia64 over the next week or two.
