Software overridable cpuid strings are getting quick commonplace in CPUs from several vendors.
I beleive the reasoning is that sometimes the lead time from manufacture to marketing is long enough that the default power-on string may not be correct, hence the BIOS can do the XP/MP descrimination, and set accordingly. (Unless you've got a crap BIOS).
If anyone believes they have a BIOS which doesn't do this correctly, (/proc/cpuinfo reports XP, and x86info reports MP or vice versa), let me know, and I'll see what I can dig up.
