According to the Shimano web page FAQ:

===========
Frequently Asked Questions

19) What cleats work with which pedals?

The SM-SH70 and SM-SH71 work best with both the PD-7410 and the PD-6500.
The SM-SH51 and SM-SH55 work with the PD-M747, M636, M545, M535, M515,
M434, M323, A525, M737 and M525. 

There are a couple usable combinations which can be substituted for
the recommended cleat:

PD-M747, M636 M545, M535, M515, M434 can use all cleats (70,71,51,55).

The PD-A525 and PD-M323 work with all cleats except SM-SH70. 

The new SH-90, SH-81/91 and SH-82/92 are only compatible with the PD-7700,
PD-6600 and PD-5500 SPD-R type pedals. 

==============

Based on this, I made the following table, which really ought to be on
Sheldon's web page (the 70/71 cleats are the standard road-racing cleats
and 50/51 are standard two-sided pedal cleats):

      M747 M636 M545 M535 M515 M434 M737 M525 A525 M323 7410 6500 SPD-R
 SH70  ok   ok   ok   ok   ok   ok   no   no   no   no   yes  yes  no
 SH71  ok   ok   ok   ok   ok   ok   no   no   ok   ok   yes  yes  no
 SH50  yes  yes  yes  yes  yes  yes  yes  yes  yes  yes  no   no   no
 SH51  yes  yes  yes  yes  yes  yes  yes  yes  yes  yes  no   no   no
 SPD-R no   no   no   no   no   no   no   no   no   no   no   no   yes   

So the direct answer is that only the multi-release SH71 cleat will work
both with your A525s and with Ultegra 6500 SPDs.

I don't see what purpose the one-sided A525s serve. Svelt one-sided
road-racing pedals make sense for the extremes of weight shaving and
corner clearance, but these are not met by the heavier and clunkier A525.
You are just giving up the two-sided convienience of the M535 or M515 with
no benefit in return except possibly the bogus claim that they are `road
pedals' not `MTB pedals'
