I was under the impression that in an optimal setup (jackd -d alsa -d
hw:$X), the jack buffer/period setup is identical to what the driver
uses to communicate with the hardware.

In fact, examining the ALSA driver parameters[*] while jackd is
running confirms this for both the UCG-102 USB and the ice1712-based
PCI interface here.
