We were looking at the dmidecode output from qemu-kvm pre-seabios and current qemu-kvm and noticed some of the strings have changed.
The main problem with this is that certain OSes are quite sensitive to system changes and avoiding to change things unnecessarily would probably be a good thing.
Which OSes do care? Windows only?
The problem with this kind of stuff is that we don't know what is sensitive and what doesn't care. Most of the Open Source OSes should be fine, but still Windows is a pretty big customer in the virtualization guest space.

I guess the Socket Designation in particular might have been done for a reason?
Otherwise, if there are no objections, I'll look at adding some patches to make it more backwards compatible.
Is the different ID displayed on the same VM configuration (esp. -cpu option) ? The value is gained by calling CPUID so it should not be different.
Which pre-seabios qemu-kvm bios are you comparing to?
Hmmm good point, I'll go back and dig some more on this.
