After going back to the RAID driver, in an effort to make Standby and
Hibernate function properly I wasn't happy because it just said "Raid
Controller" for the device. It used to specify Silicon Image etc. So I
went to SI's website and downloaded and installed the lastest RAID
driver for the device, version 1.0.60.0, dated 2/2007. It's not
correctly described, and the install went a lot easier because there was
a .cpl file, which Windows was looking for. Will have to monitor the
ACPI behavior.
