Gods, I hope they have reconsidered that in their 64-bit chips. The 32-bit hash chains may be ugly, but the architected 32/64-bit MMU stuff is just so incredibly baroque that it makes any other MMU look positively beautiful ("Segments? Segments shmegments. Big deal").
I still have the occasional nightmares about the IBM block diagrams "explaining" the PowerPC MMU in their technical documentation.
There's probably a perfectly valid explanation for them, though (*).

(*) Probably along the lines of the designers being so high on LSD that they thought it was a really cool idea. That would certainly explain it in a very logical fashion.
