           Summary: Fixes for loadable modules and strict aligned access in
                    int10 module
           Product: xorg
           Version: unspecified
          Platform: Other
        OS/Version: NetBSD
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Server/general
        AssignedTo: xorg-bugzilla-noise at freedesktop.org
        ReportedBy: skrll at netbsd.org


While getting X working on my NetBSD/cats which is an ARM based platform I've 
needed to fix the following. 
 
- IOPortBase needs to be declared somewhere other than 
    xc/programs/Xserver/hw/xfree86/common/compiler.h 
    xc/programs/Xserver/hw/xfree86/drivers/chips/util/AsmMacros.h 
 
  otherwise each module ends up with their own version. I chose 
 
    xc/programs/Xserver/hw/xfree86/os-support/bsd/arm_video.c 
 
  this is inline with the powerpc variable ioBase. 
 
- the int10 module with cause unaligned accesses which aren't allowed on most 
  architecture. My patch prevents these on ARM only, however.
