No.

>From the D.N.A.R.D. User's Guide: 

- supported are (table page 4-4, translated to megabytes):

 8 +  0
 8 +  8
16 +  0
16 + 16
32 +  0
32 + 32

- on page 4-5 there is a sentence claiming that the Firmware doesn't set up
page tables to map more than 64 MB of memory, so unless you change the firmware
you can't use more than 64 MB.

- It is not clear to me whether 64+0 would work, or whether PAL changes would 
be necessary to use bigger DIMMs, too.
