I agree that the fc7 version string looks strange, because
there are other things in the fc7 dmesg which are clearly from 2.6.21,
such as this:

< ACPI: Core revision 20060707
---
> ACPI: Core revision 20070126

Perhaps you can try building a kernel.org 2.6.21 kernel and running
it on your FC6 install?

The ALI15X3 stuff exists only in the working FC6 dmesg:

FC7 looks like it is using libata instead:
