did that (before) - no success.
(i also had problems with that - some gfx cards ago ;-)

yes. pc164. the most unsupported alpha ever :)

hmmm - found the following in the web
(http://www.cs.columbia.edu/~bm/3dcards/3d-cards1.html#CS12).
it looks as delta is (like gamma) a geometry processor for 3d operations.
xfree86 (4.2.0) just added support for that chip.
also the linux kernel (2.4.17) dri (direct rendering
interface/infrastructure) detects it.

CS12) 3DLabs GLINTdelta
The information in this section was taken from a press release
provided by Dave Baldwin
(dave_baldwin@3dlabs.com.)
The GLINT Delta is 3DLabs 3D Geometry Pipeline  Processor.  It 
accelerates GLINT or PERMEDIA-based Graphics Boards up to three times
by off-loading up to 70% of the 3D geometry processing load into a
hard-wired 100MFlop processor that delivers 1 Million polygons/second
for under $50. 
3DLabs claims that when used on a high-performance PC, using a Pentium
Pro  processor, GLINT Delta-based designs have been measured to
deliver  over 750K polygons per second via OpenGL.  
For intensive 3D  graphics applications, GLINT Delta significantly
improves overall  system performance by freeing the CPU from demanding 3D
pipeline  calculations -- providing more processor time for application
level 
processing.   
The Delta is implemented as a PCI bridge with full PCI master
capability.  It acts as a front-end processor to GLINT or PERMEDIA and
processes the setup calculations for 3D primitives such as lines and
polygons.  GLINT Delta's advanced design includes support for
texture-mapping, anti-aliasing and 16, 24 or 32 bit Z buffering - all
with high-precision, sub-pixel accuracy. GLINT Delta's processing
throughput is up to 1 million texture-mapped, Z-buffered polygons  per
second.  GLINT Delta supports full byte-swapping and is compatible
with PC or Macintosh systems.
GLINT Delta provides a glueless, single-chip geometry solution  for GLINT
300SX or PERMEDIA.  GLINT Delta also supports multiple  GLINT rendering
processors -- also without glue logic -- for high-end desktop, arcade and
VR
applications seeking unmatched rendering  performance.  The combination of
GLINT Delta and two GLINT rendering  processors enables board vendors to
provide dual- GLINT 3D  acceleration on a single PCI board, seamlessly
combined
with full  Windows performance and functionality.
PERMEDIA does not require GLINT Delta to provide class-leading 
performance,
however the ability to combine the two devices in a  low-cost designs
enables
board vendors to provide a wide-range of  price/performance options at
performance levels far beyond other 3D  chip offerings.   
GLINT Delta is software compatible with the GLINT and PERMEDIA  families,
and 3Dlabs' extensive range of software drivers is already  available for
GLINT
Delta-based boards.  These drivers include:  Windows NT, Windows 95, OpenGL
on
Windows NT, OpenGL on Windows 95,  Heidi from Autodesk, Direct3D from
Microsoft, CGL from Creative and  QuickDraw 3D and QuickDraw 3D RAVE from
Apple.  The drivers for  Windows NT and OpenGL are available on Intel,
Alpha,
MIPS and PowerPC processors.

still trying to get it running - the RAMDAC seems to be a problem...
will modify the glint driver of xfree86...
