A new patch is attached to this message that synchronizes the RELENG_4 amr 
driver with CURRENT, minus the SMPng locking and amd64/ia64 ioctl 
compatibility stuff.  The fixes and their corresponding file revisions are:

Greater than 4GB support
         amr.c           1.55, 1.56, 1.59
         amr_cam.c       1.10
         amr_pci.c       1.24
         amrvar.h        1.23

ioctl fixes for LSI management tools
         amr.c           1.60, 1.61

Fix module unloading
         amr_cam.c       1.12
         amrvar.h        1.24

Check for NULL amrd_sc in amrd_dump
         amr_disk.c      1.32

Support for LSI 320-2E PCI Express controller
         amr_pci.c       1.27
         amrreg.h        1.8
         amrvar.h        1.26

The only part of the patch I've tested is the >4GB support.  The rest 
compiles but I can't vouch for its validity because I don't have the 
software or hardware to test.
