Hardware compression?

No, but seriously... sounds like it may be hardware in search of a
Quirk.

Have you checked around via Google for whether there's some fancy
goobledygook the vendor wants you to put into, for example,
Solaris's /kernel/drv/st.conf? (Unless I've missed more than I
thought ignoring things since roughly 1.6, we haven't got a similar
driver config file, but, you know, rebuild your kernel.)
