Subject: hifn_795x in a MacMini?

Hi Evgeniy,

while doing "make menuconfig" on a shiny new MacMini[0] I came across the 
option for the HIFN 795x crypto accelerator. I've set:

CONFIG_CRYPTO_DEV_HIFN_795X=m
CONFIG_CRYPTO_DEV_HIFN_795X_RNG=y

and after loading the module, dmesg shows:

   Driver for HIFN 795x crypto accelerator chip has been successfully registered.

Somehow this message sounds to me, as if this MacMini does have such a 
chip. This would be surprising, as I thought the chip is a highly 
specialized one, and expensive too. Also 
there's no ../devices/ symlink in /sys/bus/pci/drivers/hifn795x. Still, 
why would the driver load into the kernel when there's no such chip?

Thanks,
Christian.
