     Revision History:
+    Rev  3.26, January 16, 2006 Jes Sorensen
+       - Ditch all < 2.6 support
     Rev  3.25.1, February 10, 2005 Christoph Hellwig
        - use pci_map_single to map non-S/G requests
        - remove qla1280_proc_info
        - Integrate ql12160_set_target_parameters() with 1280 version
        - Make qla1280_setup() non static
        - Do not call qla1280_check_for_dead_scsi_bus() on every I/O request
-         sent to the card - this command pauses the firmare!!!
+         sent to the card - this command pauses the firmware!!!
     Rev  3.23.15 Beta March 19, 2002, Jes Sorensen
        - Clean up qla1280.h - remove obsolete QL_DEBUG_LEVEL_x definitions
        - Remove a pile of pointless and confusing (srb_t **) and
         - Don't walk the entire list in qla1280_putq_t() just to directly
          grab the pointer to the last element afterwards
     Rev  3.23.5 Beta August 9, 2001, Jes Sorensen
-       - Don't use SA_INTERRUPT, it's use is deprecated for this kinda driver
+       - Don't use IRQF_DISABLED, it's use is deprecated for this kinda driver
     Rev  3.23.4 Beta August 8, 2001, Jes Sorensen
