    Disable detection of crt for the smi 501/502.
    
      As described by siliconmotion, it does not work on the smi 502.
    Does it work on older revisions? Keeping <hash>ifdef'ed out for now
    as it hopefully will be corrected in a newer hardware revision.

    Implement an argb cursor using the alpha layer.
    
      The code is <hash>ifdef'ed out by <hash>if SMI_CURSOR_ALPHA_PLANE
    because the smi 502 hardware is buggy, but it appears to have worked
    for some older hardware revisions (by looking at code available at
    ftp.siliconmotion.com.tw).
      Keeping it at least for now, as it serves as a simple way to reproduce
    the problems described in smi.h.

    Add support for the reading/writing the alpha layer registers.

    Correct wrong offset value for secondary hardware cursor.
    
      Hardware cursor is still disabled in dual head mode due to some problems,
    usually when having both panel and crt mapped to the same address, what
    appears to confuse the "modes" code.
