I downloaded an earlier datasheet which did say 24MHz and a couple of ATmega48s
I got were ATmege48V 12AI i.e. 12MHz so it looks like they had problems with
24MHz operation and changed the spec.

From the new datasheet:

Changes from Rev.
2545B-01/04 to Rev.
2545C-04/0
1. Speed Grades changed:
- 12MHz to 10MHz
- 24MHz to 20MHz
