Sonnet tech support confirmed that the card blocks HD sleep commands.
It's not a deal-breaker, but still a disappointment.
I was a bit hesitant to go with a port-multiplier system, thinking that it would adversely affect performance. But both disk subsystems perform extremely well, with the RAID able to sustain uncompressed 1080/60i HDTV without a problem. You could probably get a bit more performance by not using the port multiplier, but then you are limited in the number of drives you can connect, since the densest SATA controller I know of is just 8 ports.
I'm satisfied enough with this that I'm ordering another to install into a new Mac Pro (Intel-based) system.
I'm a software developer and have sent several bug reports with loads of diagnostics but after 4 months nothing has been done.
Obviously, if I'd known their software was broken I would not have purchased this product.
