What is the status on this? The package seems to have the intel bit
masked out while looking for the AES-NI bit. This seems to be part of
1.0.2f-2. I have here an AMD-A8 (and A10) but I don't think I can get
my hands on A6 :/. Anyway. With 1.0.2f-2 I see a difference in performance
between 

  OPENSSL_ia32cap="~0x200000000000000" openssl speed -evp aes-128-cbc 
  type             16 bytes     64 bytes    256 bytes   1024 bytes  8192 bytes
  aes-128-cbc      82125.33k    89565.82k    88865.96k    90472.45k 90947.58k

and
  openssl speed -evp aes-128-cbc 
  type             16 bytes     64 bytes    256 bytes   1024 bytes  8192 bytes
  aes-128-cbc     243645.05k   294776.58k   297669.21k   309102.45k 311200.43k

Which suggests that AES-NI is use. According to [0] the CPU in question
has AES-NI available.

btw: I can start clamtk on my A8 without any trouble…
