405EX Rev D mis-identification?

[Marc Chidester]

It looks like the Rev D version of the 405EX chip without security
will be identified as a 405EXr, based on the values in the cpu_specs
table.  For 405EX/405EXr the pvr_mask is  0xffff0004 with the
pvr_value's as 0x12910004 and 0x12910000 respectively. I see that the
Rev D PVR value for the 405EX without security is 0x12911473, which
would mask out to the EXr value.

Is there an algorithm update needed or am I missing something?
