The term you are looking for is "non-fakeraid". There can't be something that requires absolutely no drivers, but the hardware raid controllers only require drivers for the storage operations, no software implementations of the RAID functionality.
LSI offers (offered) a whole bunch of SAS/SATA controllers under the LSI as well as the 3Ware brands which are/were hardware RAID. Obviously, hardly any product for the PCI bus survived until today as the possible maximum theoretical PCI bandwidth of 133 MB/s would bottleneck transfers. But you can use PCI-X controllers in PCI 3.3 Volt slots, if you really need to.
As a rough rule of thumb, anything that has at least an option for a battery-backed (or capacitor-backed or flash-backed) write cache, is a "true" hardware RAID controller.
