Linux, SL, WineX3.3+, NVidia and AGP working?

I have read that WineX 3.3+ from www.transgaming.com cvs.transgaming.org had parameters for setting AGP such as:

[X11drv]
...
"VideoRam" = "256"
"AGPVertexRam" = "32"
...

Attempting to enable AGP in SL under my old WineX results in:

INFO Creating LLAGPMemPoolNV
INFO Warning! Unable to allocate AGP memory! Disabling AGP
...
WARNING Attempting to allocate AGP memory when AGP disabled!


I downloaded the CVS and compiled it. After reading the thread here I concluded no changes were needed to the code. But I was wrong.

After compiling and using it to run SL, SL complains that it cant get an 8 bit alpha channel and screen colour goes psychodelic colours.

System: Mandrake 10.0, NVidia GeForce FX5950. My Linux logs report:
kernel: agpgart: Found an AGP 3.5 compliant device at 0000:00:00.0.
kernel: agpgart: Putting AGP V3 device at 0000:00:00.0 into 8x mode
kernel: agpgart: Putting AGP V3 device at 0000:01:00.0 into 8x mode

using wine --debugmsg +all,warn-x11drv -- newview.exe 2>SLwinex.log the SLwinex.log reports (note: Stencil was 0 not 8, PFD_GENERIC_ACCELERATED not mentioned):

in old working winex CVS:

Failed fix attempt of opengl.c:

/* stencil bits */
glXGetConfig( gdi_display, vis, GLX_STENCIL_SIZE, &value );
//ppfd->cStencilBits = value; //commented out!
ppfd->cStencilBits = 8; //force to 8 for SL

after compiling and running SL
Stencil is reported as 8 and PFD_GENERIC_ACCELERATED returns, according to wine debug, but SL logs still show:

"INFO GL buffer: Color Bits 32 Alpha Bits 0 Depth Bits 24"

How do we make SL detect Alpha Bits?
How do we make AGP work for SL thru WineX?

to optain wineX v3.3.2 use:

cvs -d:pserver:cvs@cvs.transgaming.org:/cvsroot login

Password is cvs

cvs -z3 -d:pserver:cvs@cvs.transgaming.org:/cvsroot co -r winex-3-3-2 winex

This works for my NVidia FX5950

Notes:

'config' file parameters:

[X11drv]
...
"VideoRam" = "256"
"AGPVertexRam" = "32"
...

I have yet to establish what numbers are correct for AGPVertexRam for my card.

If wine fails to run with the error:
wine: lstat /home/<user>/.wine/wineserver-<server name>/socket : No such file or directory

try this option first:

export LD_ASSUME_KERNEL=2.3.98

then try

export LD_ASSUME_KERNEL=2.2.5


I have not tested if win.c needs modification to let SL install as mentioned here.

yay! now to get 3d sound working...
