Pentium II mobile cores

[isa-d]

a question
Pentium II mobile processor are with two product code, 80523 and 80524, so is it the first a Deschutes (Pentium II) core and the second a Mendocino (Celeron) core?
but in this case may be the first not a Deschutes but a Covington (80523 Celeron) core?

80523T Mobile Pentium II (Deschutes, 0.25 micron)
80524T Mobile Pentium II (Mendocino core, 0.25 micron)

80523 Desktop P2 is codename Deschutes (0.25um, 0k on-die L2, 2.0V core voltage)
80523 Desktop Celeron is codename Covington (0.25um, 0k on-die L2, 2.0V core voltage)
80523 Mobile P2 is codename Tonga (0.25um, 0k on-die L2, 1.6V core voltage)
80524 Desktop Celeron is codename Mendocino (0.25um, 128k on-die L2, 2.0V core voltage)
80524 Mobile P2 is codename Dixon (0.25um, 256k on-die L2, 1.5V-2.0V core voltage)

Now I 'heat gunned' a BGA SL23Y: http://www.cpu-world.com/cgi-bin/IdentifyPart.pl?PART=SL23Y&PROCESS=Go

It's supposed to be a 80524 and called a Mendocino at the information page. It has a rather large die and I've seen the same size dies marked as /256 - which should be Dixon P2's.

My question is: has anyone ever de-lidded a desktop Mendocino to see what's behind the heat spreader? The mobile Mendocino's die is larger than it supposed to be so either:

a.) Mobile Mendocino is basically a Dixon-128 and not the same as the desktop Mendocino.
b.) It's the same as the desktop Menocino. In this case they're all Dixon-128 parts so I don't even feel sorry for Intel suffering making those desktop Mendocinos back then anymore. They willingly dug their own grave with those huge (and cheap) Dixon Celerons even though they rarely used half of the cache that made them so big

[Okay, I know that Dixons are not that big but they definitely look big for cheap CPUs.]
