94 implements a hardware byte swapper using a 32-bit datum.

120 This adds a pci quirk to disable Ricoh MMC Controller. This
121 proprietary controller is unnecessary because the SDHCI driver
122 supports MMC cards on the SD controller, but if it is not
123 disabled, it will steal the MMC cards away - rendering them
