##Sun PGX32
This is a re-badged [Tech Source]( Raptor GFX 8P, which in turn is a bog standard [3D Labs]( Permedia 2 with Sun firmware in ROM.
The board has 8MB RAM and a 33MHz/32bit PCI interface.

    OpenFirmware name: TSI,GFXP
    Common header:
    0x00: 0x00093d3d 0x02900006 0x03800001 0x0000ff00
    Vendor Name: 3D Labs (0x3d3d)
    Device Name: GLINT Permedia 2V (0x0009)

There is nothing really remarkable about this card, Xorg's [[glint]] driver Just Works(tm) and the [[pm2fb]] driver provides an accelerated console.<br>
The firmware is rather buggy:

* the linebytes property is always the same as width, even with more than 8 bit colour depth
* some property names have trailing spaces
* the [[color!]] method does nothing so we can't change the palette in 8 bit

There are workarounds in [[genfb]] and [[pm2fb]] for the first two problems, and [[pm2fb]] doesn't depend on firmware calls to access palette registers.
