So far we seem to hit a few different problems when upgrading kernels. 1) mkinitrd may need changing, e.g. the raid4, raid5 and raid6 modules were combined into raid456 a while ago, breaking mkinitrd completely on raid machines. 2) some modules may now work that were broken, but they need new options, like snd-hda-intel which now works on my acer notebook if "probe_mask=1" is added to the module options. 3) like (2) but options may need to be removed. suddenly drivers that worked refuse to load becuase they no longer recognize options that used to be valid. I'm especially concerned about (2) and (3) because there doesn't seem to be a system in place to update driver options after the system is installed. We can collect the needed changes but the logic to do all of this is in anaconda, and can only be applied during system install, as far as I can tell.
