I don't think that your situation means linux is not ready for the desktop.  
You are trying to attempt something fairly complicated.  The integrated VIA 
video chips do not work overly well.

Obviously you are into gaming.  I don't know of many serious windows gamers 
who use an on-board video card.  You get what you pay for with oboard cards.  
IMO.

As for the VIA chips.  I have an integrated KM400 video chip.  I had problems 
getting it to work properly.  By default X used the vesa driver ... 
everything worked fine I just had no acceleration.  You can get the X drivers 
from VIA's website for all the integrated chips, although they are built for 
a limited number of distributions, and therefore they are only specific 
kernels, and 2.6 is not yet supported.

I recently upgraded to 2.6 kernel, and now I have no acceleration _again_.  
Apparently from the message boards you can make it work, by custom building 
the kernel and X and on and on.  I wasn't into that.  If it really bothered 
me that much ... I'd just go and get a well known supported video card.

My desktop works absolutely fantastic without acceleration.  I have email, 
web, office suites, P2P, development for all of my work, multimedia (sound, 
imaging, CD burning).  So I can't watch Microsoft Format videos in full 
screen mode with MPlayer.  That's not a fault of the linux desktop, but 
rather a fault of the hardware I'm using.

Alan Cox wrote a via driver for use in the kernel.  The kernel driver is not 
the issue, it's the X windows driver, and from what I have seen from Alan's 
messages, it will be quite a task to get the HW acceleration to work.

VIA can't even get it right.  I installed _their_ driver and I still had wonky 
things going on.  I never have the same problems under the vesa driver ... 
there's just no full screen.
