  1.  DEC 21030


  o  The DEC 21030 is supported by X11R7.5.  The driver is now partially
     accelerated. The built-in graphics on the Multia is supported in
     8-plane mode, and PCI cards with 8 or 16 MB framebuffers are
     supported in 24-plane mode. TGA2 (aka PowerStorm 3D30/4D20) cards
     are not currently supported.

  o  Current Known Problems


     1. Virtual desktops and multiple modelines do not work. You should
        specify only one modeline.

     2. Hardware cursor is only supported on systems with the BT485
        ramdac, ie the Multia.

     3. After the server has been run using the hardware cursor, the
        Linux TGA console cursor (which also uses the hardware cursor)
        is shifted down by one pixel. This problem does not affect Linux
        kernels 2.2.10 and above, which do not use the hardware cursor.

     4. The XAA PolySegment() method is buggy. If you experience server
        crashes with SIGFPE, or server hangs, try disabling it (see
        below).


  o  The following options may be specified for the 21030 driver:

     BusID
        Currently it is necessary to specify the BusID so that the
        server will find the card.  Check /proc/pci and look for the
        bus, device, and function numbers in the 21030 section. On a
        Multia, this should be "PCI:0:11:0".


     MemBase 0x???????
        If the server does not detect the base address of the 21030,
        then check /proc/pci for the 21030 and look for the
        "Prefetchable 32 bit memory at 0x???????" and enter this as your
        MemBase setting.


     Option
        Disables acceleration.


     Option
        Disables the hardware cursor.
     Option
        Disables the XAA PolySegment() method.
