[gentoo-doc] enabling CONFIG_SYSVIPC in the kernel for nvidia and others.

[Dale]

Hi,

I ran into a problem yesterday and now that it is fixed, I wanted to 
mention it here to see if you think the docs need to mention this.  This 
is a brief version.  I built a new system that has a Nvidia card and a 
LG monitor.  I could not get the GUI to work and the nvidia drivers to 
load properly.  This is the relevant error:

(EE) Failed to initialize GLX extension (Compatible NVIDIA X driver not 
found)

The problem turned out to be that CONFIG_SYSVIPC was missing in the 
kernel.  This is not just used by nvidia but it appears that at least in 
some cases nvidia needs that in the kernel.  This is not mentioned on 
the nvidia driver docs page.  I think it should be mentioned but it may 
also be needed somewhere else and someone may want to test if ATI needs 
the same option.

I'll leave it up to the experts to decide where this should be.  If it 
turns out that ATI needs this too, maybe it should be in the xorg 
configure section to cover both Nvidia and ATI.

Let me know if you need more info.

Thanks

Dale
