No, Itanium specifically eschewed OpenFirmware (IEEE1275-1994, which is ANS Forth based) in favor of inventing EFI, which would develop into UEFI later. Among the reasons: no interest in bytecode (UEFI now has EBC), no ACPI support (IEEE1275 predates ACPI by a decade, Intel didn't bother), protecting Intel's "Independent" BIOS Vendors from having to compete in an existing market (there were several OpenFirmware vendors). Most OF implementations are now open source, we collected them at www.openfirmware.info.
